Using Ten is a mental math strategy for subtraction that involves changing a number to "10" and then adding on the remainder to solve a subtraction equation. For example, in the equation 13-8, a student would first perform the equation 10-8=2, and then add 3 more to make a total difference of 5.

Using Ten is an important strategy to learn, as it will enable students to use mental math to calculate differences using a sequence of steps. Additionally, learning this strategy will equip students with the skills needed to use similar strategies for other equations. For example, once a student has mastered how to "use ten," he might begin to "use twenty" for an equation such as 24-19=___. As students master this strategy, you will likely notice them using it in many different circumstances.

This mental math strategy unit includes materials and printables that will help your students learn and practice the strategy of using ten. Included is independent seat work, flashcards, center activities, large group kinesthetic learning activities and more!

Additionally, at the end of this unit you will find a special BONUS section that will provide practice with using multiples of ten. This can be used as a follow up to the main activities in this unit, or as enrichment for students that are easily grasping the main concepts in this unit.

Enjoy!

These units are fabulous. I wish I had them earlier this year when I taught this strategy. I'm using them now for students who are struggling. I like the three different levels of worksheets. It is great for my students who need a challenge. Thanks!

Hi Shelley. I have a question about Using Ten for mental math subtraction. Our district has adopted the My Math curriculum and for the most part I like it. We are suppose to be teaching the using 10 strategy this week and I am considering skipping this lesson. It just seems to be too difficult a concept for my first graders, and I don't want to confuse them. I understand using 10 for addition but for subtraction just seems to be too abstract for them. Also, we haven't done anything with place value yet so using the base 10 blocks would also be difficult. I noticed on your YouTube video (which, by the way, is very helpful) that you suggest that strategy for grades 2 or 3 and up and am surprised that the My Math curriculum introduces it in first. I am curious as to your thoughts. I don't want them to not be prepared for something when they get to 2nd grade. Thanks!
Hi there! Well, here are my thoughts: YOU are the teacher and YOU are the one who knows your students the best. I am a huge advocate for not introducing too much, too quickly. Your students will benefit from learning a couple of strategies really well, rather than a whole bunch of strategies that they have not totally mastered. If the decision is up to you, then I would wait. Get them really practiced up with Counting Up/Back, Using Doubles, and Thinking Addition. Keep practicing, and reinforcing. IF you feel later in the year, that they are ready for a new strategy, then introduce it, but if not do not feel bad! You are doing your students a service by allowing them to master skills before introducing ones that are too hard/abstract.

Also, remember that one of the biggest goals of mental math is to create students who are mathematical thinkers. So by teaching them even 2 strategies, you are preparing them for future grades because they will be able to think and reason differently than students who have only been taught to memorize.

You sound like a really great teacher. Keep up the good work!

Shelley
This is so helpful! Thanks so much!
