Learning Resources Interlocking Gram Unit Cubes combine hands-on play with foundational math learning. This set includes 1,000 interlocking plastic centimeter cubes in 10 colors, with each cube weighing 1 gram. Students can use the cubes for counting, sorting, patterning, place value, measurement, area, volume, multiplication, geometry, and STEM activities. The snap-together design makes it easy to build models, create patterns, explore mathematical relationships, and visualize concepts such as ones, tens, and hundreds. Ideal for kindergarten, 1st grade, elementary classrooms, math centers, homeschool learning, intervention activities, and small-group instruction, these versatile manipulatives support both visual and tactile learners. The included activity guide provides additional learning ideas, while the storage tub keeps cubes organized between lessons. Designed for children ages 6 and up, Interlocking Gram Unit Cubes make abstract math concepts easier to understand through active exploration.
