Two-Digit Addition and Place Value

In math today, we introduced the concept of two-digit addition. We did this by using our base-10 blocks. We created silly stories about animals and how much they would weigh together. Then we represented the weight of each animal with base-10 blocks and added the blocks together. We did not focus on the regular math notation for this yet. We are working on building a deep understanding of place value and how addition works and will focus more on how to write it in symbols (25 + 36 = 61) at a later time. (I did write some problems using that notation so some children may begin using the symbols now. It just depends on how ready they are for that step.) Check out the pictures below for some examples.

Our Arts and PE class next week is Art.

This is a way that you can draw the blocks to use this system at home.
