Spreadsheet math generally focuses on ratio and proportion to develop the concept of fraction. But fractions is such a big problem in today’s curriculum that it seemed only right to use the power of spreadsheets to help students and teachers to gain some fraction-sense. This is a very simple spreadsheet that uses histograms to compare fractions. We expect students to play with this and to put in different fractions and guess which ones will be bigger or smaller and then check their guesses. This Lab only works on Excel Spreadsheets.
