Number Line, by MLC vs Owlet

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. Describe intervals between points on the line using forward or backward jumps above and below the line. Jumps can be labelled with their values or left blank. Add custom tick marks to the number line to show equivalence or compare number values. Show strategies with drawing and annotation tools. Hide elements of the sequence shown on the number line, which challenges students to use what they know about number relationships and computation to identify those missing elements. This virtual number line is an open-ended educational tool, ideal for elementary classrooms and other learning environments that use iPads.

In addition, set the starting value of the line, including using negative values. • Add and manipulate forward and backward jumps, above or below the line. • Label jump bars, manually or automatically, to show intervals or hide labels altogether. • Add custom tick marks and values to blank number lines. • Hide and reveal numbers on the number line. • Hide and reveal jumps, numbers, and other elements with resizable covers to create your own problems and model strategies. • Use the drawing tools to annotate work and show understanding. • Add equations, expressions, and descriptions with the math text and writing tools. • Share your work by saving an image or providing a share code to others.

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.
