### Divvy Up

Divvy Up is an interactive game that helps students build a concrete understanding of partitioning two dimensional shapes into equal pieces. This hands-on practice with symmetry establishes a foundation for later work with fractions and division. Students must partition two dimensional shapes into two, three, and four equal parts by drawing lines. Teachers can configure the settings of the game according to the student’s needs and grade level. First grade students can focus on dividing shapes into halves and fourths, while second grade students continue on with partitioning into thirds. Additionally, the game helps students identify symmetrical figures, draw lines of symmetry, and explain why figures have symmetry. Teachers can choose whether children will practice with simple 2D geometrical shapes, or more complicated symmetrical figures, including images of real objects and tangrams. Children are asked to draw lines of symmetry by connecting dots. The game checks the student’s responses by performing the folding test and showing a related animation. This fun and engaging game is ideal for promoting students’ hand-eye coordination, hand stability, and middle-line crossing. Their visual perception skills are improved by drawing lines and connecting the dots on screen.
