K vs Owlet

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: GlowGrid is one of a series of apps that use the Owlet GlowBoard manipulative. The specific focus of GlowGrid is using the GlowBoard to understand arithmetic operations like addition and subtraction. Students turn the dials on the GlowBoard to model arithmetic operations with the colored lights. The GlowGrid app communicates in real time with the GlowBoard, so the app reflects student work with the GlowBoard. GlowGrid has five modes for five arithmetic operations: Addition, Subtraction, Multiplication, Division, and Division with Remainders. Each operation has five different activities. - Explore: Students turn the dials to model arithmetic equations on the GlowBoard. The tablet shows the students the equation that they are modeling. - Make: The app challenges students to use the operation to make a target number in different ways, i.e. Make 11 in 9 different ways. - Solve: The app challenges students to solve arithmetic problems with the GlowBoard. - Find: The app challenges students to solve missing number problems with the GlowBoard. - Create: Students can create their own problem and use the GlowBoard to demonstrate the solution.
