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.

The long blocks represent a ten and the little cubes represent a one.

When you don't have base 10 blocks, you can draw the blocks like this to help you solve a problem. The sticks represent a ten and the dots are ones.
