Extend the Show Me activity and Equivalent Fractions section described in Part 2 using the complete set of fraction strips.
Observe students as they fold and label their fraction strips and complete the Show Me activity in Part 4 of the lesson to see whether they can represent fractions (E1), name fractions (E2), represent improper fractions and mixed numbers (E5), and find equivalent fractions (E8), with fraction strips. Use prompts to check for understanding. For example, when students are showing the fraction 3/5, ask:
- What is the denominator in this fraction? What does it tell you? (The 5 tells you how many parts are in the whole strip.)
- Do the parts have to be the same size or can they be any size? (They have to be equal parts.)
- What is the numerator in this fraction? What does it tell you? (3; It tells you that 3 parts are showing.)
For fractions greater than one, ask:
- Work with a partner to show 13/10 in two different ways. (Students can show all of a red strip and 3/10 of a purple strip to show the mixed number 13/10. They can actually use any strip to show one whole. For example, students can show one purple strip and 3/10 of another purple strip to show 13/10 or 13/10.)
- For 13/10, show me where the 10 in the denominator comes from. (Each whole is divided into 10 equal parts.)
- For 13/10, show me where the 13 in the numerator comes from. (Students can count the 13 parts that are showing.)
Show Me can continue to be played to provide targeted practice. The Workshop in Lesson 7 also provides targeted practice with these Expectations.
