Slide-A-Round Math Manipulatives are a visual, hands-on way for students to visualize the abstract concept of rounding numbers up to 10,000,000, equivalent fractions in 12ths and 16ths, decimals, weight, elapsed time, and money. Students incorporate a series of movable slides with visual cues such as lines and arrows to assist in approximating and rounding numbers. Teachers often administer this assessment as a benchmark or post-test/review of required common core math standards.
