Hello Families,
Recently your first graders have been investigating number sentences and number stories with missing addends. For example, they must solve problems like the following:
There were 10 apples on the tree. Some fell off and rolled away. Now there are 7 apples left on the tree. How many apples fell off?
Though the numbers appear small, students are challenged with understanding the structure of the number sentence! They have to visualize what happened first, next and last. They have to decide whether numbers need to be compared, put together or taken apart.
This week we are exploring this type of thinking with missing addend number sentences.
10 - ____=7
We are learning different games to help with this process.
Today's and tomorrow's game is called "What's under my cup?"
The poster below illustrates all of the strategies that students suggested during our math discussion!

This is a complex process and we want students to use whatever strategy makes sense to them AS WELL AS to challenge students to think of all of the different available strategies they can use to solve this problem
I am really excited about this game I found on a BBC website. It is called the Little Animals Activity Center. The game has three different options addition - subtraction - addition and subtraction and students can move through three levels (using dots, single digit numbers, two digit numbers).

My computer asked me to download a plug in of some sort, but it was free! Totally worth it. Students will play this game as well in school on Thursday.
ENJOY!
