Designed for 4th grade, but great to use with 3rd to 6th grade fraction units.
Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction mode
This learning activity includes
• 1 explanation page to use at the math workstation
• 8 task cards with pattern blocks,
8 extension task cards to use without pattern blocks
• 2 student answer sheets,
Assessment with key
• Paper templates you can use with color copy paper or construction paper to create your own fraction pattern pieces.
This learning activity was designed to concretely use Pattern Blocks to determine how to rewrite an improper fraction as a mixed number. Students will work on 8 tasks cards to discover how to decompose an improper fractions as pieces that can be combined to make a whole.
This concrete fundamental understanding is limited to fractions with the denominators, 2, 3, 4, 6, and 12. Yet… the learning can then be extended to other denominators once children have CREATED their own understanding and generalizations.
It is the teacher’s job to lead a class discussion about any generalizations or patterns that students were able to create. It would be a natural next step to practice or test their generalizations with fractions with a denominator NOT practiced with pattern blocks.
(The purple and brown Pattern Block pieces can by found at the following website. http://www.enasco.com/product/TB15438T I brought two sets to add to the pattern block set I already had in my classroom.)
