This educational set helps children develop number concepts up to 120 while reinforcing addition and subtraction skills through grid-based number patterns. The package includes a 120-number mat, three inflatable cubes for interactive play, and 64 frames with corresponding markers for hands-on learning. Four T-shaped frames are included to visually demonstrate ten more/less and one more/less number relationships. Designed for children aged 6 and older, the materials provide multiple approaches to building foundational math skills through structured activities and visual aids.
