To Half or Half Not
Jump into equivalent fractions using these fun scenarios for mathematicians to solve. First, they use geoboards to find different ways to divide a rectangle in half. Then, an alien from the planet Fractional is after one half of their...
Curated OER
Finding the Shape of a Web
Students examine spider webs they find as they explore outside. They make T-chart of the shapes found in two different webs and draw them on geoboard paper. Next, they measure length and width of a spider's web before checking to see if...
Curated OER
Geoboard Squares
Learners 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 (and...
