# Using Two Sided Counters for Guided Math Lessons

**Two sided Counters!** Everybody needs them. They are so great. You can use them to model all the operations. They are officially called Double Sided Math counters. They usually come as red on one side and either white or yellow on the other. You can also just make them by spray painting lima beans. You can also print out paper ones http://www.teachervision.fen.com/teaching-methods/printable/44640.html?detoured=1

**5 Frames** -Use them with 5 frames. Teach them in small groups with the actual frame and then move to the internet games. In the games on this site, you work on different strategies, such as counting, missing addend and adding with 5 as a landmark number. http://illuminations.nctm.org/activitydetail.aspx?id=74

**10 Frames** – Use them with 10 frames. Teach them in small groups with the actual frame and then move to the internet games. In the games on this site, you work on different strategies, such as counting, missing addend and adding with 10 as a landmark number. You also work on teaching the visual representation of using lucky 8 and lucky 9 otherwise known as compensation. Ten frames allow students to see what they are doing. http://illuminations.nctm.org/activitydetail.aspx?id=75

**Addition **-Students can use these counters to practice addition problems. Each color is a different addend. They model with the manipulatives. I also set up problems where they have to take an equation and build the model.

**Equivalent Names** – Students toss the beans and then color in the amounts on this *Math Their Way* bean template… http://www.center.edu/BLACKLINES/001-061/033-039.pdf. There are templates for equivalent names from 4-10. I have the students make equivalent name books. I also have the students to match different pictures with different equations. I also have them to use the mats to build the different equations.

**Comparing**– Students toss the counters and then compare the amounts of each color.

**Patterning** – Use the counters to make different patterns…abc, abab, abcd, ababbabbb, abc

**Fractions**– Have students toss the counters and then write the fractional part of each color. http://www.math-lesson-plans.com/support-files/day8fractionswithtwocolorcounters.pdf

**Probability **– Give the students one double-sided counter and have them flip the counter 10 times and record the colors. They discuss how many times it lands on each color and discuss the probability of each color coming up.

**Negative Numbers** – http://www.math.nmsu.edu/~breakingaway/Lessons/subtractcounters1/subtractcounters.html

*Two color counters come in plastic, in foam, as magnets, in circles, and in bean shapes.*

Hi Dr. Nicki,

You might get tired of hearing from me, but I am overflowing with ideas from the two-sided counters post. I was most interested in the positve and negative numbers link. Fantastic. I haven’t quite figured out the e-manipulative game or is it just for counting. Can you do operations with this? The 5 and 10 frames are the best!! Our 1st graders will benefit from these strategies. Mathematastic!!

Hi,

I am so glad that you comment all the time! Keep commenting! You can use the game for positive and negative numbers as well. You can also model the different operations with them. I love the word Mathematastic!

Happy Mathing,

Dr. Nicki

Keep the posting up. I never thought I would find an individual that had close to the same grasp of worldly knowldege , however, you are that beacon of hope in humanity!I hope you continue to bring your knowldge and enlightenment to the world and never let your expression be squelched! Live strong!

What nice things to say. I am humbled by your words.

Thank you,

Dr. Nicki
