Use slides 12-44 of the Introduction to Fractions PowerPoint to revise halves, quarters, thirds, fifths and eighths. Revise the function of the numerator (the number of pieces of the whole you have) and the denominator (the number of pieces that make up the whole). For each fraction, reiterate how many pieces are needed to create a whole.
Provide each student with either a label or a circle segment from the Fraction Wheels (there are 29 pieces altogether; it may be necessary to select an appropriate number of pieces, according to the number of students in the class). Allow the students to walk around the classroom so they can find all of the matching parts to make a whole circle. They should also find the appropriate label for their fraction.
Once the students have found their group, ask them to sit down and make the whole circle together, using the fraction pieces. Ask each group:
Which fraction does your piece represent?
How many of these pieces were needed to make the whole circle?
Provide each student with a copy of the Fraction Flags Worksheet. Monitor and support the students as they complete the worksheet. Once completed, these could be added to the classroom fractions display.
