Watch the video to see how to fold a square of paper to create a flower. On my calculator I divided one whole number by another whole number and got the answer 3. DEE undertook the division. Which route has the smallest product?

    Unit fractions (fractions which have numerators of 1) can be written as the sum of two different unit fractions. For example.To try to overcome this, the Egyptians made lots of tables so they could look up answers to problems.

    Consider the equation 1/a + 1/b + 1/c = 1 where a, b and c are natural numbers and 0 < a < b < c. Prove that there is only one set of values which satisfy.They were based on the unit of weight which was called the as.

    The Egyptians expressed all fractions as the sum of different unit fractions. Here is a chance to explore how they could have written different fractions.Special Sums and Products Find some examples of pairs of numbers such that their sum is a factor of their product.

    These KS2 tasks encourage learners to take a closer look at fractions. This task offers opportunities to subtract fractions using A4 paper.Of course, by their very nature, rich tasks will also provide opportunities for children to work like a mathematician and so help them develop their problem-solving skills alongside this conceptual understanding.

    To be correct, one of the unit fractions must have a denominator which is 1 more than the denominator of the original unit fraction, and the other unit.Children are invited to 'say what they see' to prompt discussion related to statements about the paper.

    Explain that the ancient Egyptians didn't write fractions with a numerator greater than 1 but expressed every fraction as the sum of different unit fractions.Can you tell us what each of them will have?

    The Egyptians wrote all their fractions using what we call unit fractions. A unit fraction has 1 as its numerator (top number).For example:.Forum Nrich unit fractions

    Such tasks also provide valuable opportunities for you to assess where children have got to in their thinking and so support the next steps on their learning journey.
