Addition Games that teach:
Add equations with two to three digits and powers of 10, 100, 1000.
First your child needs to understand:
Counting forward and backward to and from 1000.
Count by 1's, 10's, 100's, and 1000's forward and backwards.
Once understood, play these games:
(1) Think of the hundred chart as a number line ( you can even use one row to add and subtract small numbers). The chart can support your child while you ask difficult addition and subtraction problems.
Take turns making up problems for each other to solve. Try adding and subtracting by tens first (counting up or down) then the ones (counting left or right.) If your in the car use numbers you spot on the road as a starting spot- it makes the activity much more engaging.
(2) Look for addition and subtraction patterns. 3+7=? Now go to 43+7, 73+7, 83+7. What do you notice? What do 10-7, 20-7, 30-7, etc. have in common? What other patterns can you make? Kids are amazed when they see these patterns.
(3) Make a puzzle with the chart, cut in up into pieces and have your child put it back together. Cover up numbers( use a sticky or dot) in the chart and see if your child knows what they are.
(4) We love to play games with arrows, for example start at 71, go back 2(← ←), go right 1(→), then up 1(↑), what number do you have? My kids love to make up arrows for me.
(5 ) Count by 25's (think of quarters), 10( think of dimes), 1 (think of pennies), 100(think of dollars). You can even use the chart to add up things- when we go through the drive-thru I have them get out their hundreds chart and add the price of each item(we round the numbers) and see if we can get close to the total. It is a great way to spend time waiting for your food.
If you were like me you probably look at some of the math your child brings home and say to yourself, "I learned how to do it the old fashion way borrowing/carrying and that worked out for me. Why does my child have to learn this way?" The short answer is that by mentally adding larger numbers later on it will pay off ten fold. It will help in long division, algebra, etc. You must just trust that is vitally important to help your child mentally add.
