Math Skills: Conversions
In this conversions worksheet, students use metric unit conversions to solve fifteen word problems that involve converting from one unit to another.
Curated OER
Dimensional Analysis
In this mathematics worksheet, students apply dimensional analysis to solving each problem. They identify the conversion factor and describe a unique characteristic of a conversion factor. Students also identify the unit in the final...

SI Units and Conversions Between Them
For this SI units and conversion worksheet, students are given five problems to solve. They convert from one SI unit to another.
Skills Workshop
Ratio, Scale, and Proportion
Converting units is an excellent example of how math relates to our everyday tasks. The resource prompts mathematicians to use baking, cooking, and other daily activities to discover how to make larger quantities of each ratio or recipe.
Illustrative Mathematics
Floor Plan
A multi-step problem has learners finding the actual area based on a scale drawing and then converting units at the end. Two different solution choices are listed depending on the preference on which step to start first. Both methods can...

What is a Nanometer?
Teams learn about the size of a nanometer by measuring objects and converting those measurements. A instructional activity then tests the groups' abilities to use nanometers by having them determine the size of objects that are too small...

First Consequences of FTS
Challenge the young mathematicians to find the exact coordinates of a dilated point. The fifth segment in a 16-part series introduces the class to the converse of the Fundamental Theorem of Similarity. Scholars use the theorem to find...
California Mathematics Project
Model Solar System
The sun's diameter is 864,337 miles—challenge learners to create a scale model of the solar system that fits in your classroom. Scholars make conversions and work with scientific notation as they create the scale model.

Ecological Footprint
Eighth graders discover their own ecological footprint and create a plan for reducing this figure. They extend this to the school and community to see how they are doing on this scale. They discuss the concept of the ecological...
Beyond Benign
Build-A-Math
We can't build our dream house yet, but we can definitely build a model. Scholars use floor plans to build models of their dream homes. Cardboard is as good as any material for this purpose.
