# How to Use the Decanomial Bead Bars – Primary Verion

April 23, 2020

So you printed out the Complete Decanomial Bead Bars, and now you're ready to dive in start using them! Here are a few lessons you can show your child with the bead bars:

## 1. Play the Snake Game

For this lesson, you will be making combinations of 10 with the colored bead bars and converting the colored snake into a golden one. Create a "snake" with the bead bars, making sure that each combination of beads equals 10. Tell your child, there's only one rule in this game:

"Everytime you get to 10, you must exchange for a ten bar."

Make sure to keep the colored beads on the side of the mat after exchanging so you can verify your answer!

The decanomial beads are a great way to practice addition facts! I don't even have to explain this one, it's that easy. You can use a sheet of paper, write down random equations and let the child add!

## 3. Do the Multiplication Layout

This lesson is super fun and one of my favorites! Chose a number to work with... For example, 4, like we did in the video. Take four one time and lay it horizontally.

"Four taken 1 time is... 4."

You can use a toothpick or some tool to count the beads... or just plain old fingers too.

Continue doing the same thing until you reach 4 taken 10 times.

## 4. Practice Subtraction Facts

Practicing subtraction facts with the beads is pretty simple! Let's do the example in the image above.

"I have 9... if I take away 7, how many will I have left over?"

Place the 7 bar underneath the nine bar and cover that portion with your hand.

"I have two left over!"

Have fun doing lots of random combinations!
