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.

Alternating chains

Children create chains of alternating positive and negative numbers and explore the patterns in their totals. 

+ Details
Pence and pounds reversed

Children discover patterns in the differences when pounds and pence are reversed.

+ Details
Four of the best

Children use an incomplete magic square to explore patterns in the addition of four decimal numbers. 

+ Details
Triangle co-ordinates

Children draw different types of triangle on co-ordinate grids and reflect these in the y-axis.

+ Details
LCM squares (1), Get to the root (2)

LMC squares (1): Children use trial and improvement to find the smallest possible total on a square of Lowest Common Multiples. Get to the root (2): Children use their fluency in mental multiplication to explore the patterns of digital roots in multiplication.

+ Details
Big triangle of fractions

Children add fractions with related denominators and find equivalent fractions to identify patterns.

+ Details
Dozen divisions (1), Fraction frenzy (2)

Dozen divisions (1): Children use short division to divide three-digit numbers with consecutive digits by 12. They reverse the digits in the three-digit number and repeat. They then find the difference between the two answers. Fraction frenzy (2): Children multiply proper fractions by whole numbers in a mulitplication grid and look for patterns.

+ Details
Mobile differences

Children use trial and improvement to find the largest and smallest possible differences using numbers selected to given criteria.

+ Details
Roomy boxes

Children cut squares from a square piece of paper, fold up the sides to form an open cuboid and find out which size will hold the most 1cm3 cubes.

+ Details
Decimal differences

Children subtract pairs of numbers with consecutive digits and different numbers of decimal places, and explore patterns in their answers.

+ Details
Division remainder patterns

Children look at patterns of remainders in four-digit numbers when dividing by numbers 3 to 6. They can establish a rule.
