SugarByHalf - Investigating 'Lite' Foods

Australian Curriculum content description:

Math, Years 5 & 6

Year 5

• Use estimation and rounding to check the reasonableness of answers to calculations (ACMNA099)

Year 6

• Make connections between equivalent fractions, decimals and percentages (ACMNA131)
• Select and apply efficient mental and written strategies and appropriate digital technologies to solve problems involving all four operations with whole numbers (ACMNA123)

English, Years 5 & 6

Year 5

• Understand how to move beyond making bare assertions and take account of differing perspectives and points of view (ACELA1502)
• Use comprehension strategies to analyse information, integrating and linking ideas from a variety of print and digital sources (ACELY1703)

Year 6

• Identify and explain how analytical images like figures, tables, diagrams, maps and graphs contribute to our understanding of verbal information in factual and persuasive texts (ACELA1524)

Relevant parts of Year 5 Mathematics achievement standards: Students check the reasonableness of answers using estimation and rounding.

Relevant parts of Year 6 Mathematics achievement standards: Students connect fractions, decimals and percentages as different representations of the same number and solve problems related to this. They make connections between the powers of 10 and the multiplication and division of decimals and calculate common percentages.

SugarByHalf promotes action to reduce sugar-related diseases so that we can live better, stronger and healthier lives.

Their message is simple: to reduce added sugar consumption by half. Eating too much added sugar is a key driver of serious health problems including obesity, type 2 diabetes, heart disease, tooth decay, dementia and mental health conditions. A poor diet also puts children behind their peers, affecting brain development, sleep and ability to learn. Poor diet choices ultimately mean that this generation of children could be the first in modern history to live shorter lives than their parents.

Much of the added sugar in our diet comes from the processed foods and drinks we consume. On average, we consume 14-16 teaspoons of added sugar per day. Teenagers consume more than 20 teaspoons per day. The World Health Organisation says we should limit our daily added sugar intake to 6 teaspoons for good health. To put that in perspective, there are 4 grams of sugar in one teaspoon. If something has 20 grams of sugar, that's 5 teaspoons of sugar. 

This English lesson focuses on developing the skills and knowledge students need to critically consider messages about food and drink they are exposed to, thereby equipping them to be able to make healthy choices.

Talking about health

• Be mindful of students who may experience weight stigma. Some students may be sensitive to conversations around weight, body size or shape. Terms including obesity, weight issues, weight-problem and fat can be stigmatising for some people because they assign blame. It is important to note individual preferences around language vary. Research has shown using the terms ‘weight’, ‘weight gain’, ‘healthy weight’, ‘unhealthy weight’, and ‘high BMI’ are preferred as better alternatives.
• Be mindful about how you use the word ‘diet’. We recommend focussing students on the positive impacts of healthy nutrition and healthy lifestyles which help us to have stronger bodies and minds, feel good and sleep well.
• Steer students away from any focus on appearances by communicating that appearance does not determine your worth. We recommend the fact sheets from the Butterfly Foundation on body image tips.

• Avoid using labels such as obese or diabetic. Refer to people living with diabetes, people living with cancer, people with high BMI etc
