Maths at Woodbridge Junior School follows the Maths No Problem Textbooks – This term we are focusing on developing our skills in measure, ratio and algebra.
Our next topic, percentages, we will be exploring how to calculate percentage of numbers and quantities. We will be learning about how to solve for percentage change and use percentage to compare amounts. In the first lesson, we will be finding the percentage of a whole number. This will involve both division and multiplication skills. We will then move on to finding the percentage of a quantity, measured in amounts such as litres and millilitres. In the third lesson, pupils will be looking at difference and percentage change before finally moving on to using percentage as a way to compare numbers and amounts.
Later, we will be comparing quantities, including numbers, objects, fractions and mass before moving on to solving word problems. In the first six lessons, we will use bar models and concrete materials to compare amounts. We will be using both pictorial and abstract multiplication and division to support their learning while simplifying and comparing ratios. In the final three lessons, pupils will be solving word problems involving ratio by constructing bar models to support their understanding.
Finally we will learn some of the conventions of algebra in the context of patterns and real-life problems. The chapter begins with lessons describing patterns and using a letter to denote a variable. We then move on to write expressions using the four operations and fractions, while continuing to look for patterns and determine rules. Throughout the chapter, the expressions become more complex, including more than one variable with multiple steps. We write and evaluate algebraic expressions and use formulae to solve problems in real-life contexts. The chapter ends with pupils using word problems to write equations with two unknown values solving a range of equations.
