Addition and Subtraction Fact Family Pyramids – Sums 10 – 19
These 34 Pyramids are a motivating addition to a math center. Working with a tutor, parent, with another student, or independently, is fun with a 3 dimensional figure. Each figure displays a fact family for addition and subtraction. The base of the pyramid shows the number family. Each face contains part of a number sentence for that family. Print on colored card stock to add to the appeal.
There is a strip for each family showing all the addition and subtraction facts for that family. Also included are a few pages of answer strips for students to write the number sentences for a family if you choose to include those in your center.
Use your imagination for making games or serious practice with these pyramids.
They do take time to cut out and construct. Print on card stock. I suggest doing the construction a little at a time, then introduce one family at a time. If you need all the families at once, I suggest having some 4th or 5th graders help during an indoor recess, or during an art class. Some younger students can assemble them, however, many younger students find making the creases difficult.
The patterns need to be cut out carefully on the black lines. Then, folds need to be made on all the dotted lines, and sharp creases need to be made on the dotted lines. A thick craft glue works better than the standard school glue. Be sure to put glue right up to the dotted line on each of the four tabs. Put the pyramid together and let it dry, pressing the edges together if they start to pull apart while drying. Then enjoy the learning.
