Students need to have a deep understanding of fraction
concepts. Our textbooks often focus on
the basic skills. It’s important to
provide opportunities for mathematical discourse, reason abstractly, and construct
viable arguments. I adapted problems from various sources to create five stations
providing opportunities for elementary students to explain their thinking about the concept
of a fraction, the meaning of fractions, and reason about equivalence and
addition.

The stations address these Common Core State Standards:

• CCSS.Math.Content.3.NF.A.2 Understand
a fraction as a number on the number line; represent fractions on a number line
diagram.

• CCSS.Math.Content.3.NF.A.3 Explain
equivalence of fractions in special cases, and compare fractions by reasoning
about their size.

• CCSS.Math.Content.4.NF.A.1 Explain
why a fraction

*a*/*b*is equivalent to a fraction by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.
• CCSS.Math.Content.4.NF.A.2 Compare
two fractions with different numerators and different denominators, e.g., by
creating common denominators or numerators, or by comparing to a benchmark
fraction such as 1/2. Recognize that comparisons are valid only when the two
fractions refer to the same whole. Record the results of comparisons with
symbols >, =, or <, and justify the conclusions, e.g., by using a visual
fraction model.

You can use the stations as journal entries, group work,
formative assessment and purposeful practice.

Let me know if the stations work well for you!

How do you challenge students to think deeply about fractions?

I love this freebie. Can’t wait to use this in my classroom. I’m glad I found your blog through Maniac Mondays!

ReplyDeleteThank you, Breanne! Look around ... my exploration of elementary math is new. Most of my work is in secondary math. But I tutor the younger set which spurs me to consider elementary topics!
