2nd grade math question

Show how you would explain "Make a 10"
to someone who never heard of it.

Count the toes on both feet?

Draw a straight line and a circle.

Using two 10 frames. You would use chips or pennies to fill in the first 10 frame with the first number in the number sentence for example 9 if the number sentence is 9+5 then in the second 10 frame you put in the second number(5)

then have the student move the chips from the second ten frame to fill in the first that is making a 10. It then makes it easier to add because 10 is a magic number that when you add to it you can still see the number you added.

show 8 broken key is 8 show several ways.

To explain the concept of "Make a 10" to someone who has never heard of it, you can use a simple visual representation.

Start by drawing a number line with numbers from 0 to 10. Explain that when we want to add two numbers together, sometimes it's easier to break one of the numbers apart to make a 10.

For example, let's say we want to add 7 + 5. Ask the person to find the number 7 on the number line. Then, explain that we need to add 5 to this number. But instead of starting from 7 and counting up 5, it's easier if we break apart 5 into 2 and 3.

So, you can ask the person to find the number 2 on the number line and move 2 spaces to the right from 7. This will bring them to 9. Then, ask them to find the number 3 and move 3 more spaces to the right from 9. Now, they have reached 12.

Explain that by breaking apart 5 into 2 and 3, they were able to make a 10 with the 7 and 3 left over. Therefore, 7 + 5 is equal to 10 + 2, which is equal to 12.

This strategy of making a 10 can be helpful when adding numbers that are close to 10 or when solving other types of addition problems.
