How does subtraction work? Count on Crayola® Erasable Colored Pencils to help you figure it out!
1.
Find about 10 objects, such as balls, paper cups, or stuffed animals. Point to each object and count how many you found. Now take one of the objects away. How many do you think are left? Count them again. Take away two items next. How many are left now? Count to find out. You're doing subtraction!
2.
Show what you're doing with these number ideas using pictures on paper. With Crayola Erasable Colored Pencils draw at least 10 things. Count how many you made. Write down that numeral. Ask someone for help if you're still learning how to write numerals.
3.
Erase one or more of your pictures with your Colored Pencil eraser. How many things do you think are left now? Write down that number. Does your answer make sense? Count your objects to find out how many are left. Write down that number, too. Do the numbers match?
4.
When you can accurately figure out how many are left each time, ask someone to show you how to write number sentences. Number sentences use symbols to show the operations you can do, such as 7 - 1 = 6.
5.
Continue erasing your drawings until there are no objects left. Or keep drawing new things and erasing others. Subtract 1, 2, 5, or more items. Isn't subtraction fun?
