This is a daily routine designed to help students with the understanding of fractions and decimals with denominators of 10 or 100. Each calendar piece has a blank 100's grid. The teacher will shade in an amount. Ex. 3/100 and model how to write the fraction and the decimal for that amount. 3/100 and 0.03. Students will write their answers on a blank calendar page or on the 100's grid page. Each day has a different amount. It is important to remind students daily that the square is the whole and has been divided into 100 parts. When shading in 10/100, point out to students how the grid also has 10 columns and 10 rows. 10/100 is equal to 1/10. 0.10 is equal to 0.1. Assessment opportunities- A. Take 2 calendar pieces and have students to compare their size. Which is greater or which is less. B. Take 5 calendar pieces from the previous week and have students to write the fraction and decimal for each.
