Our son has been learning how to find the midpoint between two different numbers. If you're unfamiliar with midpoints, it's simply the number that is in the middle of any two numbers.
For example, given the numbers 0 and 10, the midpoint would be 5. Given 0 and 100, it would be 50. Pretty simple right?
The problems he's been doing so far use nice, easy numbers that end in 0. It makes learning the formula for calculating the middle much easier.
So what is the formula?
I'm glad you asked.
To find the middle of any two numbers, simply add the two numbers together and then divide by two. Let's use a couple of examples to demonstrate.
Say we have the numbers 100 and 200. This one is easy enough that we know the answer is 150, but let's work it out anyway.
100 + 200 = 300
300/2 = 150
There you go.
I've created six different worksheets that you can print out to have your child practice learning how to use the formula above.
They start out with easier problems and then work up to larger numbers that may be more difficult for some students. If you're child is having problems with the larger numbers, be sure to review the addition and place value worksheets.
The final worksheet is a blank template that you can use to create your own problems for your child to work on.
Using the printouts is easy. Simply write the midpoint on the dotted line between the two numbers.
