This set includes "doubles" flash cards for 1+1 thru 10+10. Each card has a picture icon that represents the answer of the doubles fact. Ex. 4+4=8 spider (8 legs) and 6+6=12 egg carton (1 dozen eggs).
Also includes "halves" facts flash cards for 2-1=1 through 20-10=10. The "half" facts include the same pictures as the doubles cards with lines to illustrate subtraction.
Cards are 4x6. Use these as part of board or calendar math or in small groups to review.
