Finding The Way Home

Subject: MathTopic: Numbers

Unit: FarmingGrade: Two

Learning Outcomes:

2.N.9. Demonstrate an understanding of addition (limited to 1- and 2-digit numerals) with answers to 100 and the corresponding subtraction by

Using personal strategies for adding and subtracting with and without the support of manipulatives.

Assessment:

Observe students while they are completing their personal strategies for addition (Adding Animals Worksheet) to ensure that they are using the manipulatives properly for the creation of their thinking. Individually students will complete the Find the Way Home worksheet to apply their knowledge of adding 2-digit numerals with answers up to 100.

Connection to Last Lesson:

In the previous lesson we had discussed different strategies for addition (using all different kinds of manipulatives.)

Flexible Grouping:

Begin as an entire class discussing the importance of recording information (to illustrate a thinking process). Following discussion provide time for students to individually create their own strategy for addition using manipulatives (Adding Animals Worksheet). After the students complete the sheet, discuss the strategies as an entire class to create a personal class set of instructions for Addition of 2-digit numbers (allow the students to explain their strategies.) Finally have students apply their learning individually through the Find the Way Home worksheet.

Activating Strategies:

Discuss as an entire class the importance of recording something. Brainstorm with the children the types of things people record (words, songs, numbers, stories, pictures). Encourage thinking of why individuals record such things (to tell a story, to remember something, to show someone else what we did, to remind ourselves what happened, to explain something, to explain what we were thinking, to remember what we tried.) Guide the discussion and emphasise to the students that recording is writing a thinking story (where we illustrate to others our thinking process.)

Acquiring Strategies:

Provide students with the Adding Animals sheet. Discuss the groupings of animals while having students point to each group. Give the students a chance to create an addition story of their own. They must show their thinking. Provide counters, ten frames, snap cubes, base ten materials, 100-charts, and place value mats. Encourage the use of a variety of materials as individuals choose animal groups to add.

Applying Strategies:

Review the strategies the children developed to add 2-digit numbers and record them as your personal set of class instructions for Addition of 2-digit Numbers. (on chart paper to display) Have students complete the Find the Way Home math worksheet. (Have materials available if children desire to use them for the worksheet.)

Learning Resources:

Student copies of Adding Animals worksheet

Student copies of Find The Way Home worksheet

Math manipulatives (counters, ten frames, snap cubes, base ten materials, 100-charts, and place value mats)

Different Ways of Learning:

Intrapersonal students work individually on worksheets.

Interpersonal class discussion (sharing of addition strategies).

Verbal/ Linguistic students share/ explain their strategies for addition of 2-digit numerals.

Logical/ Mathematical addition of 2-digit numerals with answers up to 100.

Visual/ Spatial creating our own class set of strategies for adding 2-digit numerals.

Bodily/ Kinesthetic use of math manipulatives.

Cross-Curricular Connections:

ELA Write a story about a lost cow, and how it could get home.

Art Draw a picture of farm animals.

S.S. Research cows.

Odd and Even Numbers

Subject: MathTopic: Odd and Even Numbers

Unit: FarmingGrade: 2

Learning Outcome:

2.N.2 Demonstrate if a number (up to 100) is even or odd.

Assessment:

Students will be assessed through observation. The teacher will record if students can successfully identify odd and even numbers. Anecdotal notes will be used.

Connection to last lesson:

To ensure understanding of the processes of odd and even numbers, children will have had many experiences counting and identifying if the number is even or odd using manipulatives.

Flexible Groupings:

For this lesson I will use small groups of two. Each group will be given one thirty-sided die and bingo chips. Students will play Even/Odd Snappers. In this game each player rolls his or her die at the same time. The first person to correctly add them together, say the sum out loud and verbalize whether the sum is odd or even, collects a point (bingo chip).

Activating Strategies:

Students will sing the song Take Me Out to the Barnyard and read the poem Farmer McDonald. The teacher will show students overhead transparencies of different number of animals. Students will use small dry erase boards to write and identify if the number of animals is odd and even. First students will count the number of animals shown on the overhead transparency. Next students will print the word odd or even on their dry erase board. Once students printed their answer they hold up the small dry erase board so the teacher can see. After this activity is done the teacher will then do another activating strategy where the teacher will print a number on a dry erase board and hold it in the air so students can see. Then the class will answer on their dry erase boards whether the number the teacher printed was odd or even.

Acquiring Strategies:

1. Explain that you will be playing a math game called Even/Odd Snappers.

2. Teacher explains directions to students.

3. Each player rolls his or her die at the same time.

4. The first player to correctly add them together, say the sum out loud and verbalize whether the sum is odd or even, collects a point (bingo chip).

5. In the event of a tie (ie. Both players give the answer at the same time) both players may take a point.

6. Play continues for a set period of time.

7. The player with the most points is the winner.

Applying Strategies:

A class discussion talking about what students recognized and learned while playing Even/Odd Snappers game.

After time, teacher guides students to the following generalizations:

1) An even number plus an even number equals an even sum;

2) An even number plus an odd number equals an odd sum;

3) An odd number plus an odd number equals an even sum

Extension: This time players do not say the sum, and only verbalize even or odd.

Cross Curricular Connections:

ELA: Write a farm story.

Science: Pick a farm animal and research.

Music: Sing other farm songs and move like animals to farm music.

Physical Education: Each student is given an animal to be. The students have to make that animal noise while moving around the gym looking for other students who are the same animal.

Take Me Out to the Barnyard Song(tune: Take Me Out to the Ballgame) by Judy Hall

Take me out to the barnyard. Take me out there right now. Show me the cows, pigs and horses, too. I hear an oink and a neigh and a moo. There are chickens laying their eggs. If they don't lay it's a shame. Oh, it's one, two, three eggs today, And I'm glad I came.
