Print the triangles on cardstock, laminate and cut out. Fold each corner of the triangle on the dotted line toward the center of the large triangle so the number is hidden. NOTE: I often use these without lamination. The lamination makes them difficult to fold and it is so quick and easy to print out a replacement if one gets ruined. Work on part-part-whole, fact families, and missing number activities. Begin with the triangles with dot patterns , then progress to the triangles with numerals, then to the triangles with symbols as the students gain number sense. The colored triangle corner is the whole. • Fold one corner in, either the whole or one of the
parts, and leave the other two corners open. The student should name the missing part.
• Leave all the triangles open and use them to write all the facts for that number family.
