By Claire Guidry Kinder Subtraction Math Facts Common Core Based. I’ve put this packet of subtraction problems together to help my kindergarten students gain accuracy and speed. It starts with lower level subtracting problems and works up towards larger numbers. I have found the process of starting with lower numbers and allowing the students to gain accuracy and speed then moving up to larger numbers is the key to success.
I have taught kindergarten for 8 years and have tried different methods and I have found this to work best with my teaching style. I use Houghton Mifflins GO MATH as my main source for teaching but supplement with this packet.
Before starting this packet I make sure the students have been taught how to subtract. I teach them how to subtract using fingers, objects, number line, drawings and acting out. Once I know they understand the concept of subtracting then I introduce the packet. I allow the students to use any of the methods I have taught to complete the columns in the packet. This strategy allows for varying learning styles to succeed.
I start with level one and have the students complete just one column of problems at a time. As I see the students have mastered this level then I move on to the next level.
I give the students a limited amount of time to complete the column, then move on to some other math. The aide or parent volunteer corrects the columns during this time. When I am finished teaching the other math and the assignment is done then I allow those students who did not finish the column and those who need to make corrections go back and finish while the other students move on to something fun. I find this encourages most students to be quick the first time around.
After the students have completed a “level” in class I do use this also as a homework assignment. I send 1 level home per week.
(I don’t use flashcards with the kids because I find they spend more time playing with them oppose to actually learning the answers. My GOAL is for ALL students to be successful. Doing the columns forces all students to practice the subtraction facts.)
