Math Fact Fluency

MathFactFluency   Each week, students are working towards mastering all of their addition and subtraction facts to twenty.  Students should practice DAILY to develop fluency.  Flashcards, oral drills, computer games, and written practice drills are great ways to get prepared for our weekly drills!  Fluency is essential so students can free up their brain power to do higher level math problems!

2nd grade students are expected to fluently add and subtract within 20 using mental strategies. By end of Grade 2, they need to know from memory all sums of two one-digit numbers.

Listed below are math flashcards you can download for your child to practice!  These flashcards contain addition and subtraction cards grouped by strategy.  Using strategies is A LOT more efficient than using fingers, counting in our heads (above 3) or drawing tally marks.  
The more your child knows about these facts, the better mathematician they will become! 

 *Please note:  these flashcards do not have the answers on them.  Please work together with your child to correctly answer the flashcards and write the answers on the back.
