| LESSON | SESSIONS | DESCRIPTION | SUPPLIES |
|---|---|---|---|
LESSON 1Working with Groups |
2 | Students are introduced to basic multiplication concepts. They place tiles in groups of 2, 3, 4, 5, and 6, write repeated addition number sentences, investigate the movements of constant math hoppers, and represent even numbers as the sum of two equal addends. |
|
LESSON 2Repeated Addition and Multiplication |
2 | A zoo kitchen is the context for solving multiplication problems. Students represent problems using tools or strategies that make sense to them and learn to differentiate between addition and multiplication situations. |
|
LESSON 3How Many Monkey Treats |
1–2 | Students focus on equal groups and repeated addition to develop the concept of multiplication. They create multiplication problems and number sentences as they play the game Monkey Treats. |
|
LESSON 4Zoo Sticker Arrays |
2 | Students learn how to represent repeated addition and multiplication problems with rectangular arrays and number sentences. They develop strategies for solving multistep multiplication problems. |
|
LESSON 5Share Zoo Lunches |
2 | This lesson focuses on fair share or division situations. Students use a variety of tools and strategies to solve partitive and measurement division problems. They are introduced to the division number sentence and to the division sign (÷). |
|
LESSON 6Write and Solve Problems |
2 | Students write their own multiplication and division problems related to events or character in familiar stories. They listen to Each Orange Had 8 Slices by Paul Giganti, Jr., and solve some of the problems presented in the book. |
