Answer story problems in which you add/subtract groups to make more/less and write the matching equation.
The use of a ten frame is so important. You should have one taped inside in your car, in the homework area, etc. As children realize that the 10 frame consists of 2 columns with 5 in each row, they will start to understand how addition and subtraction work.
For example if you put a specific amount of objects on one side of the 10 frame and another amount on the other side, you can combine them (physically move them together) to see the combined total. On the flip side, if you fill in the ten frame with a certain number then get rid of some (erase or remove objects) to see the leftover total.
1. Make up story problems for your child to answer, using the 10 or 20-frame. ( I often use 2 ten frames so we can use larger numbers). This seems simple but if you personalize story problems and make it silly, kids will love to play along. I use siblings, for example, your brother was cloned 6 times and 2 clones escaped how many brother's do you have left? Next you were cloned 2 times how children do I have? What if 1 of your clones got lost?
Advanced Addition Strategies:
We already counted 17 objects inside the bag. You put in 8 more.
How many are inside the bag now?
2. Put objects in a bag, count them out aloud one by one as you put them in. Have your child pick up a handful of objects, add them to the bag. Count how many there are now in the bag. Next, how many are left in the bag if I take out 3? This is a challenging addition and subtraction game, but kids soon learn ways to keep track of what is in the bag and how many there were total. We play this game in the produce section of the grocery store.
