Expanded form is an important place value concept to reinforce in second grade.
This resource includes 24 task cards to reinforce expanded form. This skill will be reinforced in a variety of ways, such as expanding a number, looking at expanded form and identifying the number, and writing expanded form from a base 10 representation.
The 24 task cards use numbers to 1000.
If your curriculum expects students to work with numbers to 1200, I have included 6 bonus task cards that you can use. You’ll find them near the end of this file.
An expanded form reference poster is also included to display in your classroom.
