Problem solving

# Problem-solving Investigations - Year 5

The problem-solving investigations below match Hamilton’s weekly maths plans. We now also provide Year 5 maths as short blocks. We will eventually be phasing out the plans, as we believe our short blocks offer you all of the same advantages and more, including the integration of the problem-solving investigations into each unit of study. Find out more about the advantages of Hamilton's short blocks.

Exasperating 80 grand

Children use all of the digits 0 to 9 once only to create pairs of five-digit numbers, with a total as close to 80,000 as possible.

Long as you like (1), Fraction pictures (2)

Long as you like (1): Children create chains of numbers by finding factors and multiples.  Their aim is to create the longest chain possible. Fraction pictures (2): Children use knowledge of equivalent fractions to work out what fraction each shape is as part of the whole picture, and which shapes are the same size.

Excellent eights

Children explore patterns when multiplying numbers with consecutive digits by 8.

7

Prime differences

Children find out if prime numbers become less frequent as we consider sets of larger numbers.
