StandardO 3.OA.A.1 Represent and solve

problems involving multiplication and division.

Repeated AdditionOpening/HookO Hula hoop groupingsO Put a multiplication

fact on the boardO Place the correct

number of hula hoops on the floor and have volunteers put the right number of people in each hula hoop or group

Repeated AdditionObjectives:O TSWBAT write multiplication number

sentences, for given equal groups. O TSWBAT multiply by using repeated addition. Assessment: Formative:

Fist to 5 Journal Question (Written assessment)

Summative TOD

Arrays

Opening/hookO Common

household arraysO Cookie tray

demonstrationO Commutative

property (flip/flop cookie tray array)

Arrays Objectives: O TSWBAT draw an array to represent and

solve a multiplication problem. O TSWBAT distinguish factors from the

product in the multiplication problem.O TSWBAT apply the Commutative Property

to multiplicationAssessment Formative: questioning, white board problems Summative: Cookie array worksheet

Multiplication to Compare

Opening/HookO 2 students: Luke* gets

a small orange that weighs 6 ounces, Jenny gets an apple that’s two times larger than Luke’s orange.

O How much does Jenny’s apple weigh? How many times bigger is her apple?

Using Multiplication to Compare

ObjectivesO TSWBAT compare two amounts by

using multiplication. Assessment Formative: questioning, fist to five Summative: Worksheet (with writing

to explain question)

Writing math stories

Opening/HookO Read Each

orange has 8 slices by Paul Giganti, Jr

O Real life examplesO Tell me what the

multiplication problem is and how you know

Writing Math StoriesObjectivesO TSWBAT write a math story for a

multiplication problemO TSWBAT solve a multiplication problem

with a drawing Assessment Formative: Metacognitive checklist, “A

bump in the road” Summative: Create your own math

stories worksheet

Compose your own story

O LD: Work in pairs, list things they like to do in real life involving 3 groups of 5. Walk them through it again and make sure they understand real life application.

Writing to ExplainOpening/HookO Teach me how to

make a PB&J (ham sandwich as alternative for peanut allergy)

O Stress the importance of explanations (riding a bike, tying shoes)

Problem Solving: Writing to Explain

ObjectivesO TSWBAT develop an explanation to

reflect their understanding of the multiplication problem.

Assessment: Formative: performance, observation Summative: TOD

TODO Henry earns $4

for raking lawns and $6 for mowing lawns. How much will Henry make if he rakes and mows two yards? Explain how you got your answer.

Differentiation: Gifted

If Brooke continues the pattern in the table, what is the first day she will exercise for one hour? Explain how you know.

Review DayObjectivesO TSWBAT use repeated addition to solve a

multiplication problem. O TSWBAT draw an array to solve a

multiplication problem.O TSWBAT compare two amounts using

multiplication.O TSWBAT write their own multiplication

stories.O TSWBAT explain how they solved a problem.

AssessmentO Foldable (Fill out)O Repeated addition: write

this in your first boxO Arrays: second boxO Draw a picture: third boxO Skip counting: fourth box

O Differentiation: O LD- 2 x 3O Class: 4 x 5O Advanced- 8 x 6

O Review packet

Final Day: Unit TestO Mix of fill in the blank, drawings

(arrays and groupings), and short answer

Overall DifferentiationO Learning disabled:

O Adhere to IEP, 504 O CountersO Same work, simpler multiplication problem (less

time consuming for them to draw out arrays and do repeated addition)

O Simplicity in word problemsO ESL: vocabulary and word problems in their 1st

languageO Gifted:

O Same work, harder multiplication problems O More thorough explanations
