Activity 01
Inquiry Circle: Partition and Label
Give each pair a set of blank shapes (squares, rectangles, circles, hexagons) and a target number of equal parts. Partners partition each shape, shade a specified number of parts, and write the corresponding fraction. Groups compare their partitions and discuss whether different-looking cuts produce equal areas.
Construct a shape partitioned into a given number of equal parts, expressing each part as a unit fraction.
Facilitation TipDuring Collaborative Investigation: Partition and Label, circulate and ask guiding questions like, 'How do you know these parts are equal?' to reinforce reasoning.
What to look forProvide students with a rectangle and ask them to partition it into 4 equal parts. Then, ask them to shade 3 of those parts and write the fraction that represents the shaded area. Finally, ask: 'What does the number 4 in your fraction tell you?'

Activity 02
Think-Pair-Share: Fair or Not Fair?
Display a pre-drawn shape with lines dividing it into parts that appear equal but are not, alongside a correctly partitioned shape. Students individually decide which is correctly divided and explain why before discussing with a partner. The class debrief focuses on the definition of equal area rather than equal appearance.
Explain how to represent a non-unit fraction by shading multiple equal parts of a whole.
Facilitation TipFor Think-Pair-Share: Fair or Not Fair?, step in during the 'pair' phase to listen for misconceptions about equal area versus congruence.
What to look forDisplay several shapes on the board, some partitioned into equal areas and some not. Ask students to point to the shapes that are correctly partitioned into equal areas and explain why. Then, show a shape partitioned into 6 equal parts and ask students to identify the unit fraction for each part.

Activity 03
Gallery Walk: Fraction Match
Post partitioned shapes around the room with some parts shaded. Students rotate and write the fraction represented by the shaded area on a recording sheet. Include non-unit fractions (3/4, 2/3) alongside unit fractions to extend reasoning. Groups compare answers after the rotation to surface and resolve disagreements.
Analyze the relationship between the number of parts and the denominator of the fraction.
Facilitation TipUse Gallery Walk: Fraction Match to highlight different valid partitions of the same shape, emphasizing that equal area matters more than identical appearance.
What to look forStudents work in pairs to draw a shape and partition it into a specific number of equal parts (e.g., 3 or 5). They then swap drawings with another pair. The receiving pair must critique the partition, stating whether the parts are equal in area and writing the unit fraction for one part. They then swap back and discuss feedback.

Generate Complete Lesson→A few notes on teaching this unit
Teach fractional parts by starting with simple shapes like squares and rectangles before moving to irregular polygons. Use paper folding and cutting to make abstract ideas tangible, and avoid rushing to symbolic notation until students can explain their partitions. Research shows that students who physically manipulate materials retain fraction concepts better than those who only observe drawings.
Successful learning looks like students partitioning shapes accurately, labeling parts with correct unit fractions, and explaining why equal-area parts may differ in shape. They should confidently identify the denominator as the total equal parts and the numerator as the shaded or counted parts.
Watch Out for These Misconceptions
During Collaborative Investigation: Partition and Label, watch for students who assume equal parts must look identical, such as rejecting a square divided by diagonals because the triangles differ from rectangular strips.
Have students fold and cut their partitioned shapes to measure and compare areas, proving the triangular and rectangular parts are equal despite their shapes.
During Think-Pair-Share: Fair or Not Fair?, listen for students who write fractions as shaded parts over total shaded instead of total parts.
Model labeling the denominator first by counting all parts aloud, then the numerator by counting shaded parts, and have partners repeat this process before writing fractions.
