Fraction Builder

Build fractions from pieces of circles and bars. Make the same amount in different ways, then go past one whole.

Levels

Level 1: Halves and quarters (about Grade 2)

A fraction is part of a whole. The bottom number says how many equal pieces make one whole. The top number says how many pieces you have.

• I can build halves and quarters
• I know 2 halves make 1 whole
• I can read ½, ¼ and ¾

I wonder: Is half of a big roti the same amount as half of a small roti?

Level 2: Thirds, fifths and sixths (about Grade 2)

Look at the bottom number to choose the right size of piece. More pieces in a whole means each piece is smaller.

• I can build thirds, fifths and sixths
• I can choose the right size of piece
• I know ⅙ is smaller than ⅓

I wonder: Which would you rather have: ⅓ of a cake or ⅕ of the same cake? Why?

Level 3: Name it (about Grade 3)

Count all the equal pieces in one whole for the bottom number. Count the coloured pieces for the top number.

• I can name a fraction from a picture
• I know which number is the numerator and which is the denominator

I wonder: Can the same picture have two different fraction names?

Level 4: Same amount, different pieces (about Grade 3)

Equivalent fractions are the same amount with different pieces. Two quarters fill the same space as one half.

• I can make equivalent fractions
• I know ½ = 2⁄4 = 3⁄6 = 4⁄8

I wonder: How many different ways can you build ½? Is there a last one?

Level 5: More than one whole (about Grade 4)

When you have more pieces than fit in one whole, start a second whole. 5⁄4 is one whole and one more quarter: 1¼.

• I can build fractions bigger than 1
• I can change 5⁄4 into 1¼

I wonder: Why is 4⁄4 the same as 1? What about 6⁄6 or 100⁄100?

Level 6: Mix and match (about Grade 5)

You can mix different pieces in one whole: ½ and ¼ together make ¾. Use as few pieces as you can for a bonus star.

• I can add fractions with different pieces
• I can find the fewest pieces for a fraction
• I know ½ + ⅓ = ⅚

I wonder: Can every fraction be built from halves, thirds and quarters only? Try ⅝.
