Addition & Subtraction Activity
This is a set of addition & subtraction cards with a recording sheet. Print the cards on cardstock and laminate them. You will need either 2 dice or a spinner. If you are adding or subtracting within 10, use a 1-6 spinner or dice. I cover the number 6 with a sticky dot and write a zero on it. If you are adding or subtracting within 18, use a 0 – 9 spinner. The children also need a dry erase marker and eraser.
These baseball cards are great for a math station activity or small math group. The children can do this activity independently while you’re with another group that needs more support. They have either a number line 0-10 or a number line 0-20 on them, for support in solving the equation. There is also a recording sheet, so you can see how the children did.
Give each child a bat card, spinner or dice, a dry erase marker, an eraser, and a recording sheet. If adding, the children will roll 2 dice or spin the spinner. They will record the 2 numbers on the baseballs, on the bat card, to show the addends. Then they will solve the problem by using the number line, if needed, and write the sum on the bat card. The recording sheet will then be used to record the equation. They will then wipe off the numbers and repeat the process. I like to give my children each 5 bat cards so that they solve 5, then erase, and then solve 5 more. That usually gives me a chance to look at the 5 cards before they erase. I encourage the children to roll/spin again if they get the same 2 numbers as in a previous problem. If using the subtraction cards, remind the children that they need to write the larger of the 2 numbers first on the card for the minuend.
