This website has a lot of great, fun and creative ideas to help students practice place value. My favorite is the ice cream cones. Students get to build ice cream cones but matching the numbers and different ways to write the numbers.
This poster aligns the words kids see in word problems with the Math operations they represent. It has helped my students translate word problems into equations that are easily solved. Could double as book mark.
Students will never forget what a pentagon looks like! Great for a decorative Math Classroom. Create pentagons with foam core, paint them shapes, put together into a pentagon. Hang from ceiling of classroom. Remember to reference this artists work!
