This product contains number puzzles for the numbers representing the tens from 10-100. Each puzzle contains a piece that has the numeral, a picture showing base ten blocks (tens and ones), and a piece showing the numeral using ten frames. To differentiate this activity, there is an additional piece that can be used that contains the number word. All puzzles are created using the same puzzle design.
This product can be used during math centers or small group instruction. To use this product, students will assemble a puzzle containing the different ways to represent each number (tens from 10-100). The number word pieces can be used for differentiation.
