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 put counters on a place value grid to make three-digit numbers, and then use logic to ensure they have made all combinations.
Children use the magic square to generate two-digit numbers and explore difference patterns. They use logic to ensure they have found all possible combinations.
Children subtract two-digit from three-digit numbers, by counting up, and look out for patterns in the numbers.
Hands and fingers (1): Children test a theory finding and using accurate measurements to the nearest half centimetre. Yukky food (2): Children use the skills of recording and analysing data to work out which food the class hate most!
Children look at fractions and make a hypothesis of which ones are closest. They then test this out by placing fractions on a line.
Children use their knowledge of inverse operations to solve a logic problem.
Children subtract the digital root of a three-digit number from that three-digit number. They think logically to try different options.
Children add pairs of three-digit numbers and look for patterns in the digital roots of the answers.
Children use mirrors and analogue clocks. They look at mirror images and record pairs of times using the digital format.
Children work together to reason and think logically to crack a code. They practise mental multiple and division strategies.
Children find numbers between 50 and 100 which they can divide by 4. They halve each number twice to find out.
