Problem-solving Investigations - Year 3/4
Hamilton provide weekly Mixed Year 3/4 maths problem-solving investigations (below). These mixed-age investigations below will be phased out when we phase out our mixed age weekly maths plans. Year 3/4 short maths blocks will be coming during Summer Term for September 2019 and will include investigations for every unit. Find out more about the timetable for Hamilton's Y3/4 maths blocks, including investigations.
Children use their knowledge of three-digit numbers, four-digit numbers or Roman numerals, rounding, and properties of numbers to work out mystery numbers.
Children subtract numbers and use this calculation to guess a friend's age.
Children add sets of three-digit numbers to find patterns in a magic square based on prime numbers.
Children find how many rectangles it is possible to draw with perimeters 2cm, 4cm, 6cm....30cm and look for patterns in the results.
18 times table - wow! (Y3): Children use the grid method to work out the 18 times table and look for patterns in the answers. Target timings (Y4): Children add or subtract ones, tenths or hundreths to reach a target number. The use mathematical resoning to choose the best strategies.
Children use clues to find an amount of money/number with two decimal places.
Children explore multiples of 3 and 4 to find divisibility patterns.
Children explore creating patterns of tiles with three asymmetrical blocks. They look for and identify lines of symmetry, creating patterns with at least two lines of reflective symmetry.
Children find non-unit fractions of multiples and look for patterns.
Children calculate the day they were born on, and other birthdays of friends and family. They then investigate corresponding months.
Use digits 1-9 once only to complete a calculation grid with given answers for each row and column.
