In-depth Investigation: Present Prices Children use logic and addition, along with some trial and improvement to solve a problem involving money. In-depth Investigation: Wonderful 1089! Children add two 3-digit numbers and subtract a pair of 3-digit numbers to find patterns. They use mathematical reasoning to begin to explain what they find. In-depth Investigation: Mobile Subtractions Children select 3 contiguous numbers from a mobile phone display and create a subtraction. In-depth Investigation: Subtraction Trios Children look for patterns in answers when subtracting 3-digit numbers from 4-digit numbers with consecutive digits. In-depth Investigation: Prime Addition Squares Children add sets of three 3-digit numbers to find patterns in a magic square based on prime numbers. These investigations will develop maths meta-skills, support open-ended questioning and logical reasoning, and enable children to learn to think mathematically and articulate mathematical ideas. These problem-solving investigations come from our Year 4 Maths Blocks. Each Hamilton maths block contains a complete set of planning and resources to teach a term’s worth of objectives for one of the National Curriculum for England’s maths areas.
