Problem-solving Investigations - Year 3
The problem-solving investigations below match Hamilton’s weekly maths plans. We now also provide Year 3 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.
Children use their knowledge of three-digit numbers, rounding and properties of numbers to work out a mystery number.
Children subtract numbers within the same century and use this calculation to guess a friend’s age.
Children use the grid method to work out the 18 times table and look for patterns in the answers.
Children use their knowledge of litres and millilitres to help them solve a logic puzzle.
Children find change from two or three notes. They explore patterns in the pence and try to explain the reason for their answers.
Children find a multiple of 50 and a multiple for 4 with a given total. They work systematically to find all possibilities.
Children explore multiples of 3 and 4 to find divisibility patterns.
Children draw a succession of perpendicular and parallel lines to create squares. They start to make predictions and test them out.
Children explore which is more, ½, 2/3, ¾, etc. of a set amount. They also fold strips to look at the fractions.
Children create 4 or 5 two-digit numbers and add these to get different totals.
Children find all possible food combinations from given lists and then decide which are ‘yuk’ and which are ‘yum’!
