Scaling Our School
Fourth graders practice estimating the length and height of buildings at their school. They then compare their estimations with the actual heights or lengths. Each student then builds a scale model using ratio to translate the "real"...
Curated OER
One Size Fits All?
Students describe the differences between an estimate and a guess. They create reasonable estimates based on comparison and activities. Students explain how estimation is helpful in showing the relative size on a scale. They also...

Scavenger Hunt
Second graders participate in a Scavenger Hunt to find out how long 1 cm is. They then find 10 objects that estimate to be 1 cm in length and record their findings on the table provided and check their estimates using a ruler.
Curated OER
Relative Ratios
Students discover that proportions are made up of equal ratios each containing the same building blocks. They, using the Internet, apply their knowledge of direct relationships and proportions to problems in planetary science.
Curated OER
Geoboard Squares
Young scholars create squares of different sizes on a geoboard. They find and describe a pattern. Students use the pattern to determine the number of squares possible on a 10-by-10 geoboard. They create squares with a horizontal base...
