Some of you know that I've been having quite a few weather related days here in southern Ohio. That means, no school for me or my children. HOWEVER, my little guy needed something to keep his mind working. Something other than video games or Roblox. He's been having a hard time with this regrouping thing. I wanted to make it fun for him, and make sure that he's grasping the concept at the same time. So I created this little pack for him.
We worked on the sorting (Regroup/Don't regroup) for both addition and subtraction.
Then yesterday we played two of the games.
He worked on the addition Spinner game.
I didn't have any paper clips at home, but have now found that I LOVE using binder clips and a pencil for spinner games. I think it was easier to spin around, and definitely easier for little fingers.
After we worked on the spinner game, we moved on to a game I called Snowball Fight.
With this game, you play against a partner. You flip over two cards. You then create the greatest 2-digit number, and then the least 2-digit number from those cards and record them. Next you write a subtraction problem using the numbers you created, and solve. Then the playing partner repeats the same steps. The person that has the greatest difference is the winner of the round.
Now my son isn't real fond of school work outside of school---what 7 year old boy is? But he really enjoyed this game. He wanted to keep playing, so that to me, means this is a winner!
The game reinforces subtraction with regrouping, and comparing 2-digit numbers. What we also discussed was the closer the number cards were on a number line (5 and 6 for example) wouldn't create as big of a difference as numbers farther apart on the number line.
For example if you turn over a 6 and a 5, you would create 65 (greatest 2-digit number) - 56 (least 2-digit number)=9 (as the difference)
If your partner turned over a 3 and a 9, they would create 93 (greatest) - 39 (least) = 54.
It brought about a little discussion about numbers and the pattern in numbers.
All in all, I'm glad I created this little pack for my son. As he worked on his Blizzard Bag today (online work from school to not have to make up as many days due to weather), he was able to do his 2-digit addition and subtraction problems without assistance. SUPER PROUD mom here!!
