I came up with this activity in response to the second grade Common Core Math Standard 2.G.A.2: Partition a rectangle into rows and columns of same-size squares and count to find the total number of them. The rectangles on these four activity pages can be divided exactly into 1" rows and columns. Your students will use a ruler to mark the edges into inches, then joins the marks to create rows and columns. They will then count the squares to find the total number. There are many sub-skil

More fun than linear skip counting exercises, students write the numbers on beads arranged in bracelets according to the rule. Six bracelets per page, six beads per bracelet. Addition and subtraction of a single digit starting from a gven number on the first bead. On pages 7 and 8, the students must figure out the rule for themselves. Page 9 is a blank master for you or your students to devise more puzzles. I would not assign them all at once... I give one or two per lesson over a couple wee

This PowerPoint will guide your students through the process of partitioning a rectangle into same-size squares using a ruler to measure columns and rows in inches. Most of it is animated and proceeds without mouse clicks. Follow up this presentation with the activity sheets posted separately: Partition A Rectangle Into Same-Size Squares: Four Activity Pages.
