Let's build our estimating skills! Students in elementary, middle, and high school LOVE this game! A class favorite! Students are shown 14 different cards and asked to estimate the percent of yellow area that is seen on the card. The cards include various geometric shapes: rectangle, triangle, circle, parallelogram, and trapezoid.
Prior knowledge needed for this game: basic understanding of an estimate, basic understanding of percentages from 1-100 (whole number percentages).
Students learning areas of basic geometric figures can take advantage of the optional challenge worksheet. The worksheet asks students to explain how the cards were made and to make their own percentage card using area formulas.
This activity is presented in two formats: cards for printing (14 color cards on 7 full sheets) and a slideshow. Choose the format that works best for your students. The cards can be used for math centers or stations. The slideshow can be used for a whole group activity.
This game works for math curriculum support, as well as enrichment. The game takes about 30-45 minutes when used as a whole class activity. Key is included.
