Number Frames help students structure numbers to five, ten, twenty, and one hundred. Students use the frames to count, represent, compare, and compute with numbers in a particular range. The frames allow students see quantities as equal groups of other quantities and in relation to benchmark quantities. This helps primary students move away from one-by-one counting toward more efficient ways of counting and computing. As students advance, custom frames can be constructed to help visualize factors, products, fractional parts and more. These virtual versions of number frames are open-ended educational tools, ideal for elementary classrooms and other learning environments that use iPads. Number frames are a key model used in Bridges in Mathematics, second edition. Online preview available at: www.mathlearningcenter.org/bridges FEATURES: • Use standard 5-, 10-, 20-, and 100-frames, or create custom frames up to 12 x 12. • Choose from a variety of counters and colors. Drag single counters — or stacks of 5 and 10 — into frames or on to the workspace. • Apply a 5s grid to frames to emphasize every 5th line and reinforce grouping by five. • Hide and reveal counters 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.
