Integer Block Kit
This 133-piece manipulative block set is the only one you’ll need for all levels of Math-U-See, from Primerthrough Algebra 1; 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. The durable cardboard storage box doubles as a carrying case while keeping blocks tidy and simplifying clean up.
Note: While it’s fun to build with our Manipulatives, please remember that they contain small parts and are not toys. We recommend them for children ages 4 and above.
