Science Second Grade Lesson Plans

February 25 – March 1, 2013

Charlesworth, Cochran, Lambright, Wimmer

2-5.1 Use magnets to make an object move without being touched.

2-5.2 Explain how the poles of magnets affect each other (that is, they attract and

repel one another).

2-5.3 Compare the effect of magnets on various materials.

2-5.4 Identify everyday uses of magnets.

It is essential for students to know that magnets can make an object move without touching the

object. Other properties of magnets are:

A magnet is solid material that attracts iron or products that contain iron like steel.

A magnet can pull objects if the object contains iron.

The magnet pulls the object using its magnetic force. This magnetic force cannot be seen

but it can be observed when the magnet moves the object without touching it. It is essential for students to know that a magnet has two poles; one on each end.

These poles are called the North pole (N) or the South pole (S).

If the poles that are alike (North to North or South to South) are put together, they repel or

push away.

If the poles that are different (North to South or South to North) are put together, they attract

or stick together.

Some magnets, for example ring magnets, do not have the (N) or the (S) marked on them

but they do have two poles that are either located on the top or bottom of the magnet.

The poles can be determined by placing the magnets together. If they stay together then

the poles are opposite but if they push away from each other the poles are alike It is essential for students to know the effect of magnets on various materials.

A magnet is solid material that attracts iron or products that contain iron like steel.

If a material does not have iron in its composition, the magnet will not attract it. It is essential for students to know that magnets are used in our everyday lives. They are found in

their homes, schools and at places where people work. Some examples of everyday uses of

magnets are:

Magnets on cranes lift heavy objects like cars in a junk yard

Some screwdrivers have a magnetic end to hold the screw in place

Magnets on the refrigerator hold student art work so everyone can see it

A compass points out the direction we are traveling and the compass needle is magnetic

The cabinet doors in our kitchen may be held shut by a magnet

Farmers use a magnet to put in a cow’s stomach to attract any metal a cow may eat. This

keeps the cow from getting hurt by the metal.

Monday:

1. Begin the science magnet unit by watching United Streaming “A First Look:

Magnets.” (17 minutes.)

review from Monday.)

3. Help students conclude that “like” poles on magnets will repel, or push away,

and “opposite” poles will attract.

4. Read 254 – 255 together and discuss.

5. Distribute handout of “Will a magnet attract_____???” Students will predict items

that a magnet will attract. (You may want to have them predict with red pencils,

so that they won’t be able to change their predictions.) Remind students of the

words in the song iron, cobalt, steel, and nickel…NOT aluminum, brass, copper,

paper, glass, or a pickle!

6. After predicting, let students use the “magnet discovery board to see if their

predictions were accurate.

7. Discuss results and why certain items were and others were not attracted to the

magnet.

Monday: Go Math Unit 5 Lesson 3

About the Math: A key component in teaching for understanding is the

conversations that occur between the teacher and the children. For these

conversations to occur, the teacher must be intentional about setting the

norms for discussion.

There are many ways of finding an answer to a problem

Everyone’s ideas are important. You can learn by listening to other

people’s ideas.

Incorrect answsers and solutions are a valuable part of learning.

Complete SMARTBoard Lesson (Includes)

Problem of the Day

Fluency Check

Engage: Show children a handful of ones blocks. As a volunteer to

trade ones blocks for tens blocks. How did you decide how to trade

these ones blocks for tens blocks? Show children 2 tens blocks and 4

ones blocks. Ask a volunteer to trade 1 tens blocks for ones blocks.

How many tens blocks and how many ones blocks are there now?

Teach and Talk: Read the problem. Then have children use base

ten blocks or base ten quick drawings to model the subtraction and

discuss strategies for solving. “Michelle counted 21 butterflies in her

garden. Then 7 butterflies flew away. How many butterflies were still

in the garden?”

o What are you asked to find?

o How can you use blocks and drawings to model this

Tuesday: Go Math Unit 5 Lesson 4

Using the Standard Algorithm for Subtraction

In this lesson, children will be introduced to the standard algorithm for 2

digit subtraction. They will be provided with a form to guide them through

the regrouping process

Remind children to look first at the ones. In this example, children should

start with the topop umber and ask themselves, “There are 3 ones. Can I

subtract 5 ones from these 3 ones?”

Discuss with children how the regrouping is recorded. They draw a line

through the 8 and write a 7 above it in the Tens column to show that one

of the8 tens was regrouped as ones. Also they draw a line through the 3

and write a 13 above it in the Ones column to show that the regrouped

ten has ben included with the ones.

Finally children should subtract in the Ones column and in the tens column

to find the difference.

Complete SMARTBoard Lesson

o Complete Problem of the Day: Emma is supposed to practice her violin

everyday. She forgot to practice 7 days last month. How man days did

she practice last month?

Differentiated Instruction- Not Included In SMARTBoard

o Language Support: Children learn correct pronunciation my repeating

sentences that are modeled by native speakers. Show children 72-

14=_____. Then tell children the steps of modeling the subtraction with

base ten blocks. Have them repeat each sentence. There are not

enough one blocks to subtract. I regroup one ten as ten ones. Subtract

the ones. Twelve minus four equals eight. Subtract the tens. Six tens

minus one ten equals five tens. Seventy two minus fourteen equals

fifthy-eight.

o Enrich: Have partners shuffle the numeral cards and take the tope

three cards from the stack. Ask children to use these three digits to

write two subtraction propknelsm ( with unknown differences) that

meet these rules)

1) Write a subtraction problem in which the least digit is 1 number is

subtractethe greatest 2 digit number.

2) Write a problem in which the greatest 1 digit number is

subtracted from the least 2 digit number.

b. 94-2

c. 24-9

Wednesday: Go Math Unit 5 Lesson 5

About the Math: Why Teach This?

The sequence for teaching children the algorithm for subtraction with

regrouping has been carefully scaffolded to support children’s

understanding. Scaffolding provides children with support needed to

understand at a particular point in their learning.

When children first explore the algorithm they use base ten blocks. Then

they are shown how to use visual models of the blocks.

As their understanding increases, the amount of support decreases. In this

lesson, children are taking the learning a further level of abstraction by

using just symbols. However, their learning is still scaffolded. Early in the

lesson, the structure of the algorithm includes labels for the tens and ones

columns, as well as boxes to record the regrouping. As children progress

through the lesson, these labels boxes drop off the algorithm structure.

Complete SMARTBoard

Problem of the Day

o Write a number with 8 in the tens place. Write another number with

8 in the ones place.

o Allow children to share their answers

Engage: Write this subtraction problem on the whiteboard 45-7

o Have children draw a quick picture to show how they would solve

the problem. As them to explain the steps in their solution.

Teach and Talk: As you read the problem below, write 36 and 12 on the

board

o “ Devin had 36 toy robots on his shelf. He moved 12 of the robots to

his closet. How many robots are on the shelf now?

How can you draw quick pictures to help you solve this

problem?

Did you need to regroup in this problem? Explain

Complete the Model and Draw:

o Ask these questions with each problem

o How do you decide if you will regroup in this problem

o How is the regouping shown in the problem?

o How is the subtraction recorded?

Practice Use page 274 On Your Own as practice and a classwork grade.

Thursday: Go Math Unit 5 Lesson 6

Teaching for Depth: In this lesson, children continue to practice using the

standard algorithm for recording 2-digit subtraction. While helping

children understand how to use this algorithm, continue to accept and

discuss multiple strategies for solving problems.

For example, for the problem 58-19, children may respond with the

following solution strategies:

The standard algorithm

Models such as base-ten blocks or quick pictures

Using known subtraction problems (I know that 58-20= 38, so if I add

back 1 to 38 then I know the difference is 39.)

Breaking apart numbers; 58-10=48

48-8=40

40-1=39

Complete SMARTBoard Lesson:

o Problem of the Day- write the difference for each problem then write two

or more facts that have the same difference. 12-5= and 9-2=

o Engage: Write 52-8 on the board. Have children work with a partner to

solve the problem. Then have one or two pairs of children explain to the

class how they found the difference. Encourage children to draw quick

pictures or use another representation to show subtraction

o Teach and Talk: As you read the problem below write 74-19 on the board.

o “There are 74 books in Mr. Barron’s classroom. 19 of the books are

about computers. How many of the books are not about

computers?”

How can you solve this problem

o Tell children that they can use one of the ways they have learned or

they can invent a different way to solve the problem. It may be

helpful to review some of the methods they used in previous lessons,

such as breaking apart, using a number line. You may wish to

encourage children to try to find a new way to do subtraction to

check the depth of their understanding. Have children explain why

their new way works.

o Complete Share and Show practice problems

On Your Own Practice Problems page 251, as daily practice for classwork grade

Friday: Go Math Unit 5 Lesson 7

About the Math: (If children ask) Children may ask why they start with the

ones and not the tens when they are finding the difference in a vertical 2

digit subtraction problem. You may want to show children 2 different two-

digit subtraction problems- a problem with no regrouping, and a problem

in which regrouping is needed. (no regrouping 57-31, and regrouping 57-

29)

Discuss that the difference can be found by starting with the tens or with

the ones when no regrouping is needed. If regrouping is needed, then

you should start with the ones, so that you can regroup 1 ten as 10 ones

before you subtract the tens.

Complete Smartboard Lesson

o Problem of the Day: Find two numbers on the calendar that have a

difference of 11.

o Engage: Write the subtraction problem 86-54 vertically on the board

o Ask these questions

Which digits are the ones digit?

Which digit are the tens digit?

o Have a volunteer find the difference.

o Teach and Talk

o Listen and Draw: Read the problem below. Then have children write

the subtraction problem they would use to solve the problem in

vertical fortmat in the first box. They do not need to solve the

problem

“There were 45 children at a party. Then 23 children left the

party. How many children were still at the party?

Where did you write the digits in the numbers of the

problem?

Repeat by reading the problems below and having children

write, but do not solve, the subtraction problems in the

remaining three boxes. Remind children that it is important to

write the digits in each number in the correct places.

“Jamie made 52 cookies for the party. There were 21

sugar cookies. The rest were oatmeal cookies. How

many oatmeal cookies did Jamie make?”

“Evan hung up 26 balloons for the party. 9 Balloons fell

down. How many balloons were still hanging up?”

“Charlotte made 46 cupcakes for the party. The

children ate 39 cupcakes. How many cupcakes were

left?”
