A fun twist on flash cards that helps kids build number sense as they learn addition and subtraction facts. Leveled for differentiation!
This downloadable file contains three sets of triangle cards containing fact families from 2 to 10.
Set One shows numbers as dots (in dice patterns)
Set Two uses numerals only
Set Three uses numerals with adition and subtraction symbols.
Each triangle has the whole of the fact family shaded. The corners of the triangle fold in to hide one of the three numbers of the fact family for missing number and part-part-whole activities.
Students move through the sets as they gain number sense. These triangles allow for differentiation when working with students on varying levels or different ages.
