The personal learning network for educators
The following materials will work as Tier 1 and 2 interventions focusing on students who have difficulty with scientific numeracy. Specifically trouble in areas concerning relative size of measurements and calculations.
Tier 1: Students will be provided with materials similar to the attached. They will cut out the objects shown and place them in a correct size order. The attached is a sample selection of objects that cover a range of sizes. Other representations will be created and used to provide practice for the student.
Tier 2: Students will view the interactive “Scale of the Universe” flash program. Students will scroll to locate the objects and record their sizes. Sizes will be recorded on the cut-outs which can then be placed in order. Or students can use the SmartBoard to place the objects in order.
Both an Excel spreadsheet that will form a paper copy, and a SmartBoard notebook version are attached.
