Winter Base Ten is a series of 15 different activities/centers with recording sheets that explore the concept of base ten. The activities use base ten blocks (or you can use coins as a substitute) to explore adding/subtracting 1, 10, or 100 to a number, forms of a number (standard, expanded, base ten form - can have students write expanded form or other equations while playing), composing numbers (looking at various forms of numbers including more than 10 of different place values to create a number - example, 7 tens and 15 ones is 85), and using a picture of a number and adding to or subtracting from the given picture.
