There are two more excellent free math apps that will be particularly beneficial to our first and second grade students as they continue to progress through this year's math units. Number Line is a virtual number line students can manipulate to solve problems. Students can use it independently or with a partner, as there is a feature to hide selected numbers on the line. Number Pieces allows students to manipulate virtual base ten blocks: ones, tens and hundreds. They can even be broken apart and fused together! Pattern Shapes is a virtual pattern block app and a great way to explore geometry and fractions. These apps give your child free access to manipulatives which you may not have at home. Instant homework helper.
