This lesson is a step by step way to show students how to express a fraction with a denominator of 10 as an equivalent fraction with a denominator of 100. Students will then use this technique to add fractions with denominators of 10 and 100. I taught this lesson with my students using their interactive math notebook. The lesson includes a preview which introduces students to the relationship of fractions and decimals. It also has numerous slides for the interactive learning part of the lesson and a process for students to practice independently. This lesson displays nicely on a whiteboard for whole group instruction or computers and tablets for small group instruction.
This resource contains 55 full color slides that focus on how to express a fraction with a denominator of 10 as an equivalent fraction with a denominator of 100. Also included are left and right side activities for the interactive math notebook. The preview slide introduces the relationship between fractions and decimals. The preview is also a hook to reading decimals. Then the interactive learning part of the lesson starts out by demonstrating place value of decimals through hundredths using concrete materials. Once students have practiced expressing fractions with denominators of 10 as equivalent fractions with denominators of 100, they will use this technique to add two fractions with denominators of 10 and or 100 by finding equivalent fractions with like denominators. Several of the slides are great visual aids to help differentiate instruction for all learners through chunking and repetition. There is also a process at the end of the lesson for students to practice independently. This process can be used as an exit ticket to see what the students have learned. Be creative and do what works best for you and your students.
