Product Description
This product was created to help students understand that numbers can be represented in multiple ways. For example, the number 487 can be represented as 4 hundreds, 8 tens & 7 ones or 48 tens and 7 ones (and many other different ways).

This product provides practice composing and decomposing 2, 3 and 4 digit numbers. The following activities are included:

1) Group 10: Numbers are modeled using place value blocks and students need to identify the number modeled. Students are encouraged to circle 10 ones, tens or hundreds to help identify the number. 3 activities are included: one each for 2, 3 and 4 digit numbers.
2) Three Different Ways: These activities are intended to be used with place value blocks or other models to help students see that numbers can be represented multiple ways. Students are given several numbers and must represent each number 3 different ways. An activity sheet is included for 2, 3, and 4 digit numbers and a blank page is included to allow teachers to write in their own numbers.
3) Build A Number: Students spin 3 spinners to create a three digit number.
4) Missing Numbers Task Cards: A number and partial information is included on each of 20 task cards. Students need to fill in the missing information to build the number shown.
5) Four in a Row: 2 different versions of this game are included- one with 2 and 3 digit numbers and another version with 3 and 4 digit numbers. Students identify numbers shown as models and in words.
6) Place Value Detectives: This is a board game where students complete missing information to compose the number 1,000.
7) Place Value Pirates: Students identify numbers represented on cards and play with a partner to determine the bigger number.
8) Six exit slips (2 each for 2,3 and 4 digit numbers) are included to use as quick formative assessments throughout instruction.
