Word Problems vs Number Line, by MLC

Part of the Math Practice Tools CFS Bundle Practice math word problems with addition and subtraction. Select problem types to focus on Result Unknown, Change Unknown, and Start Unknown. All answers are 20 or less on the iPad and 10 or less on the iPod. Select the range of sums/minuends for the problem sets. On the iPad version: • Set the range of sums/minuends from 1-5, 1-10, 1-20, 10-15, 15-20, 10-20. • Select to use only addends and subtrahend/difference to 10 or include up to 20. • Select whether or not to include zero as addend and subtrahend/difference. On the iPod version: • Set the range of sums/minuends from 1-5 and 1-10 Use manipulatives (and a "white board" on the iPad version) to help solve each problem. Includes an option to have the problem read aloud. Designed as part of the NumberSense program at Augustana College in Rock Island, IL.

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.
