This interactive tool is one of a series of tools created by Conceptua Math that are designed for teacher-facilitated instruction. Teachers work with students using this tool to help them develop fraction sense by arranging pattern blocks to explore unitizing. This tool helps students to first identify the whole and then the fractional amounts of each color represented in a given design created using pattern blocks.

Students can either create a design that reflects given fractions or enter the fraction number for each color represented in a design. A correct answer can then be viewed as a striking tessellation which promotes further discussion and exploration including concepts of equivalence and multiple representations of fractional amounts.
