When teaching simple circuits, plot current and voltage vs. time. With HandyGraph, you can set the overall size of the grid as well as the distance between grid lines. You can type instructions directly onto the same sheet as the grid. Graphs are fascinating mathematical objects in the classroom because it is easy to discover things about them, yet you are unlikely to ever run out of things to discover. Because they are made of lines with dots on each end, children can draw graphs long before they can draw numbers, and they can discover many things about graphs without being able to count.
Bar graphs are a nice way to begin.
Students in prekindergarten through grade 2 who are working on calendar activities can collect data on the weather by recording rainy, cloudy, or sunny days. They can record the data, count days, generalize about conditions, and make predictions for the future. Inc. All rights reserved .
