K-2 Math Tools A set of math tools to use in K-2 classrooms. No math problems are presented. Use the tools to solve problems from other contexts. The Tools include: marker board, base 10 blocks (1s & 10s), counters in several configuations, 10 frames, 10 bead rows, number line with 10-25 tick marks, 5x5 and 10x10 addition grids, a 100s chart, and a calculator with addition and subtraction only. You may choose to enlarge the size of the 5x5 Grid, the 10x10 Addition Grid, and the Calculator. When selecting a number in the grid 10x10 Addition and 5x5 Addtion charts highlight the number and its addends. The 10 Beads can be set to reverse or alternate the red/white beads. It’s not feasible to use all of the tools at one time, but the tools are draggable so multiple tools may be used at once. For example, the base 10 blocks and the marker board to illustate numbers to 99. The square counters may be shown in sets of 10, 20, or 30. As they are tapped, the center changes to a white square. The number line may be set to begin at any number (including negatives). You may show 10, 12, 15, 20, or 25 tick marks.

Owlet: Cube3 is an app that uses the Owlet CubeTower manipulative. Students create numbers by stacking small cubes in the columns of the CubeTower. Cube3 has five modes. Each corresponds to a different topic in place value: Tens, Hundreds, Money, Hundredths, and Thousandths. For each topic, there are five different activities. - Explore: Students place cubes in the CubeTower to create numbers that are shown on the tablet. - Make: Students are prompted to make a target number by placing cubes in the CubeTower. - Build: Students solve number puzzles. For example, students might be asked to build a number between 200 and 300 using 5 cubes. - Compare: Students create a number in the CubeTower and then compare it to a number generated by the app. - Round: Students use the CubeTower to round a number to a specified place.
