Make 15

This is an obvious development of our Make 10 and Make 20 activities.

The downloadable pdf file contains three 10 by 10 grids of numbers. The children have the challenge of finding a line of three numbers that total 15. Each board features 14 or 16 such lines of numbers.

If the sheets are laminated the children can be encouraged to work together with white-board pens to find as many as they can.

The lines which total 15 run horizontally or vertically; and the numbers (and their positions) have been chosen with care.

The sheets could also be used as a homework activity.

The downloadable pdf file includes three challenge grids together with answers. The whole lot looks like this:

Another great resource that can be used as an independent activity for the children to continue to develop their skills. Will also be downloading the Make 10 and 20.

I am excited to have this

I am excited to have this extension to the make 10 and make 20 collections. We often have an activity called "How many ways?" dealing with a particular number for the day. I can see students being excited to do make 15 and then devise their own make a number sheet.
