Number Pieces app Students use the number pieces to represent multi-digit numbers, regroup, add, subtract, multiply, and divide. Add and manipulate pieces (ones, tens and hundreds). Join pieces or break them apart to show regrouping. Add math problems onto the placemat while working. |
 |
Number Line app Number Line helps students visualize number sequences and demonstrate strategies for counting, comparing, adding, subtracting, multiplying, and dividing. Choose number lines labelled with whole numbers, fractions, decimals, or negative numbers. Or use a blank number line, with or without tick marks. |
 |
Number Frames app Number Frames help students structure numbers to five, ten, twenty, and one hundred. Students use the frames to count, represent, compare, and compute with numbers in a particular range. |
 |
Math Clock app Learners use analog clocks with geared or free-moving hands to learn how to tell time, explore jumps with count by numbers, and visualize story problems involving intervals of time. |
 |
Money Pieces app Money Pieces help students visualize and understand money values and relationships. Two versions of coins and bills are provided: virtual currency pieces that replicate the appearance and relative size of U.S. coins and the dollar bill, and area money pieces. |
 |
Fractions app Fractions lets students use a bar or circle to represent, compare, and perform operations with fractions with denominators from 1 to 100. Choose the fraction model and number of equal parts. Use a color to select specific parts to show a fraction of the whole. Reveal or hide numeric labels as needed. Superimpose fractions upon each other to compare fractions or see equal parts. |
 |
Pattern Shapes app Students use Pattern Shapes to explore geometry and fractions, creating their own designs, or filling in outlines. As they work with the shapes students explore geometric relationships, think about angles, investigate symmetry, and compose and decompose larger shapes. |
 |
Geoboard app Geoboard is a tool for exploring a variety of mathematical topics introduced in the elementary and middle grades. Learners stretch bands around the pegs to form line segments and polygons and make discoveries about perimeter, area, angles, congruence, fractions, and more. This virtual version of the manipulative is an open-ended educational tool. |
