Fraction Activities


Fractions on Geoboards

Materials: 1. Find many different ways to divide the geoboard in half and record each on the 4- by 4- squares Fractions on Grids recording paper.

2. Do the same with fourths and eighths.

3. Do the same with thirds, sixths, and twelfths and record using the 6- by 4-square recording paper.

EXTENSIONS:

Choose one of your solutions and write an explanation telling how you know the parts are halves (or fourths or eighths or thirds or sixths or twelfths)

OUTCOMES:

Candy Bar Sharing

Materials:
1. Figure out how to share the five candy bars equally among four people

2. Glue the four equal candy parts to a sheet of paper.

3. Explain how much candy each person will get.

EXTENSIONS:

Try 1 sharing the five candy bars among a different number of people. Record your results.

Fraction/Decimal Designs

Materials:

Use some Colour Tiles to create a design that is 10 squares by 10 squares.

Record your design by colouring squares on 0.5-cm grid paper.

Write fractions and decimals to describe the part of your design that is each of the four colours. Whenever possible, use tenths. For example, 30 blue tiles are 30/100 of the design; they are also 3/10 (0.3).

EXTENSION:

Find some classmates to help you make a 10 x 100 rectangle on 0.5-cm Grid Paper. (You can cut a sheet of grid paper into sections and tape them together.)

Colour the rectangle with four colours and then write fractions and decimals to describe the part of 1000 that is each colour.

OUTCOMES:

6-A2, A9

7-A7

8-A8
