Problem solving

Problem-solving Investigations - Year 6 Spring

The problem-solving investigations below match Hamilton’s weekly maths plans. We now also provide Year 6 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.

Please note, we do not provide Investigations for Year 6 Summer Term in order to make space for SATs.

Decimal pyramids

Children add numbers with three decimal places to give a number with two decimal places, then add numbers with two decimal places to give a number with one decimal before finally adding numbers with one decimal place to give a whole number.

Cycling co-ordinates

Children use a sequence of co-ordinates to create quadrilaterals.

+ Details
Riveting reversals

Children multiply three-digit numbers with consecutive digits by a two-digit number; reverse the three-digit number and repeat. They look at the difference between the two answers.

+ Details
Mean score

Children design a dice such that the mean score is 5.

+ Details
Stars and crosses

Children find totals of the numbers in shapes on a 1-100 grid, make generalisations and then write a formula to find the total of any similar shape on the grid.

+ Details
Mixed up fractions

Children add a pair of fractions, multiply the same pair, then find the difference between the two answers, looking for patterns.

+ Details
Queued cubes

Children apply a combination of knowledge of 3D shape, area and volume to solve a problem that introduces surface area.

+ Details
Geometry genius

Children use what they know about how to find the areas of triangles and parallelograms to find the areas of rhombi, kites and trapezia.

Why is it so?

Children identify a pattern in the division of a total of six numbers created using the same three digits.  They use algebra to explain why it is so.
