🔓 This is an unlocked sample!
Byrdseed.TV is open for new memberships through May 31st, 2024. Join today!
Objective
Students construct fractions from a limited number of digits in order to reach a given solution.
A set of challenging fraction puzzles from the series Advanced Common Core Math. Students begin with the solution but have to add and/or subtract three fractions to get there. These puzzles have many right answers, will promote lots of discussion, and will help students recognize patterns within fractions.
Steps
- First students will try to create fractions that will get them to 0.
- Now, using the same digits, students will try to create fractions that will get them to 1.
- Students try to get as close as possible to 1/2 – without actually reaching it.
- Now they'll try to get as close as possible to 0 – without actually reaching it.
- Then they try to get as close as possible to 1 – without actually reaching it.
- Finally, students chose their own denominators to try to add up to 1/5.
