Fraction Animals

The Ministry is migrating nzmaths content to Tāhurangi.           
Relevant and up-to-date teaching resources are being moved to Tāhūrangi (tahurangi.education.govt.nz). 
When all identified resources have been successfully moved, this website will close. We expect this to be in June 2024. 
e-ako maths, e-ako Pāngarau, and e-ako PLD 360 will continue to be available.

Purpose

These exercises and activities are for students to use independently of the teacher to practice number properties.

Achievement Objectives
NA2-1: Use simple additive strategies with whole numbers and fractions.
Specific Learning Outcomes
  • Dividing by sharing into equal sets (equal subtractions)
Description of Mathematics

Proportions and Ratios, EA (Stage 5)

Required Resource Materials
  • Homework with answers (PDF or Word)
  • Practice exercises with answers (PDF or Word)
Activity

Prior knowledge

  • Sharing by dealing
  • Recall basic addition facts, including doubles knowledge. For example, 50 + 50 = 100, 3 + 3 + 3 = 9

Background

Halving as the opposite of doubling may be a worthwhile piece of learning that can develop from discussions around the answers to exercise 3, where students are just halving numbers.
Remember that students who have not reached stage 6 in the "basic facts" domain have not learned all of their basic multiplication facts, so a multiplicative strategy based purely on the numbers may not work for all students.

Comments on the Exercises

Exercise 1
Asks students to solve word problems that involve finding unit fractions of a set.

Exercise 2
Asks students to solve word problems. These word problems are more complex than Exercise 1. Students are asked to identify the fraction and then the answer.

Exercise 3
Asks students to solve a set of problems that asks them to find one half of a number.

Exercise 4
Asks students to solve a set of problems that asks them to find one third of a number.

Exercise 5
Asks students to solve a set of problems that asks them to find one quarter of a number.
