In this resource students must reason about introductory fraction concepts: equal parts, fractions on a number line, equivalence, numerators and denominators and fraction bars. This is aligned to the third grade common core state standards, but would also be appropriate as a review or practice for fourth graders.
This resource is here to help students engage in math talk, practice for the SBAC, PARCC or other standardized tests, and to work through the Standards for Mathematical Practice. In this activity, students decide for themselves whether six statements are true/false about a given puzzle. You can then have them engage in math talk to defend their thinking, and critique the reasoning of others.
Why work on reasoning activities?
The Standards for Mathematical Practice put a focus on the thinking processes of students. There is also some pretty strong research suggesting that students should be engaged in student to student math talk for at least 65% of your math lesson. Giving students these tasks allows them to form their own thoughts, and then work with a team to defend their thinking. If you make it a regular part of your classroom routine (once a week or every other week) students will become more comfortable with math talk.
The puzzles are also fantastic problem solving, critical thinking and deduction activities. This is also a wonderful test prep activity since the Smarter Balanced Assessment Consortium (SBAC) and Partnership for Assessment of Readiness for College and Careers (PARCC) assessments are heavy with problems in which students assess the reasonableness of statements given to them.
How long does this activity last?
Depending on the ability level of your students, each individual activity can take anywhere from 15 to 30 minutes. There are 10 total puzzles in this resource.
How do I assess this project?
You can assess what the students do individually if you have them glue their strips to the true/ false template. If you pull together small groups, you could also assess students on their group work skills and level of participation in their group.
How and when do you use this problem type in class?
There are many ways you can use this activity:
Fast finisher activity
Intervention block activity
Small group work
Homework for students
Gifted and talented small groups
Whole class activity
Parent volunteers can work one on one
Included in this resource:
Information for the teacher pages: CCSS alignment, and a sample lesson plan.
10 puzzles, and 10 answer keys with explanations for the false statements.
These puzzles are challenging, and fun! If you have any questions, or find any problems with your purchase, please contact me as soon as possible so that I may fix any errors.
