# Math Moves!

Investigating fractions, ratios, percentages, and scale becomes a job for your entire body in Math Moves! Experiencing Ratio and Proportion. The exhibition stimulates visitors' mathematical imaginations and provokes math-related movement and gesture as it seeks to build mathematical abilities, interest, confidence, and skills. Math Moves! exhibits are hands-on, open-ended, and fun. Each encourages conversation, supports shared use, and was designed for accessibility.

Math Moves! was developed by the Science Museum of Minnesota in partnership with the Museum of Science in Boston, the Museum of Life and Science in Durham, NC, and Explora in Albuquerque, in collaboration with the Center for Research in Mathematics and Science Education at San Diego State University and TERC in Cambridge, MA.

Math Moves! is funded by the National Science Foundation.

Partner Motion
Work with a friend to graph your relative rates of motion. Watch as your speed and position are recorded on a screen. Can you get good enough to draw simple pictures with your body motion?

Shapes in Circles
Close your eyes move a sprocket around a circular chain. How can your hand be tracing a square or triangle when it’s moving around a fixed circle?

Sensing Ratios
Take the challenge! Create graphs by manipulating two tone generator arms, listening to the tonal relationships and watching your graph develop on the screen.

Scaling Shapes
Use blocks to “scale up” a variety of shapes by doubling height, width, and depth. From the basic building unit of a block come a variety of shapes and levels of difficulty, offering a challenge to all.

Movie Ratios
Create stop-motion movies, and then play them back at double or half speed. What happens if you take four shots of every scene before moving props to their next position?

Half, Whole, Double
Using your whole body, figure out how to adjust the size and shape of your shadow. Grow your shadow into a monster as you play around with the concepts of half, whole, and double.

Drawing with Gears
Use a set of proportional gears on an ingenious drawing machine to create beautiful and mathematically complex designs. Work out the math if you dare!

Circle Ratios
Make colorful, digital cycloid designs using proportional drawing wheels. Predict what shape will result when you use a drawing disc that is one-third the circumference of the drawing frame it traces around.
