adding numbers 1-10

This week the boys and girls learned a new strategy using a tool we carry with us everywhere we go, our hands! 1R students practiced putting some fingers up and keeping other down to solve addition problems working with numbers 1-10. We traced the hands of a partner and did a paper art project for the hallway to share the new strategy we learned.

1R students continued to expand their math knowledge by working with groups of ten. Each student practiced this using math cubes. The boys and girls each made one tower of ten. Leftover cubes led us to a discussion about the tens and ones places of two digit numbers. We documented how many "tens" and "ones" we each had, then practiced combining and reading our final numbers.

We love a challenge!

Students applied this new knowledge to a practice game using ten frames followed by an activity done in small groups. Looking at various ten frame cards, the boys and girls wrote down the matching number sentences on their own white boards. We had fun with this as we became faster and faster at the number sentences! The students later worked in small groups to build as many towers of ten as they could with the cubes they had. We practiced counting our total number of cubes and discussed the digits we saw in the ones, tens, and hundreds places for each group's total. It was a fun challenge to then try to split these cubes evenly among our group peers!
