Teacher guide reSolve: Algebra: Odds and Evens

TLF ID M021833

This sequence of two lessons focuses on developing students' understanding of the properties of odd and even numbers. Students explore the results of adding and subtracting odd and even numbers and use these results to make generalisations. They then apply this generalisation to solve problems and to explore patterns. The sequence is outlined in detail including curriculum links, vocabulary, materials needed, discussion points and student resources such as templates. This sequence is part of the reSolve: Maths by Inquiry program.

Educational details

Educational value
  • This resource is extremely valuable for supporting the Number and Algebra strand of year 4 mathematics. The lessons are focussed on challenging students to investigate and use the properties of odd and even numbers to solve problems.
  • The resource is also of considerable value for the content description about finding unknown quantities in number sentences involving addition and subtraction. The activities invite students to investigate odd and even numbers by examining the outcomes of addition and subtraction steps in a number of different contexts.
  • The resource is also valuable for supporting the Numeracy general capability. The lessons provide multiple opportunities for students to apply skills in estimating and calculating with whole numbers to solve and model problems using efficient mental and written strategies.
