The Integer Block Kit is the foundation for the Math-U-See Curriculum. Students use these manipulatives from the introductory level (Primer) all the way through Algebra 1. These color-coded blocks allow students to visualize math operations and demonstrate concepts.
This 133-piece set includes 20 ones and tens, 13 fives, and 10 each of twos, threes, fours, sixes, sevens, eights, nines, and hundreds blocks, plus the Decimal Street™/Block Clock poster.
 
Box is showing a little wear and tear - but the set is full and in near perfect condition.
