Help your students become Number Ninjas!
This system uses triangle flashcards to help your students use the relationship between multiplication and division to become fluent in both!
Triangle flashcards focus on OA.7 - fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division or properties of operations. By the end of grade 3, know from memory all products of two one-digit numbers.
To use the flashcards, a student places the cards face down. The student picks a card up by placing their pointer finger on a corner and covering the bottom of that corner with his or her thumb. To solve the problem, the student looks at the numbers that are not covered and follows the operation to solve the equation.
To check mastery, students take a 1.5 minute test on each set of cards. If they answer the facts correctly within the time, they get a badge for that set of facts to put on their level up tracker. The cards are grouped into several levels and once they have received badges for each fact set of a level they get to level up!
The easiest way to tackle these facts is in small chunks. The cards can be color coded so that students can focus on one or two sets of facts at a time. Once they have mastered a set, they can level up and move to the next color!
