A temperature changes from 3°C to -2°C overnight.
integer change
Count the change across zero carefully.
Example: The temperature dropped by 5 degrees.
Use positive and negative numbers in practical situations and connect them to movement on a number line or coordinate grid.
Integers help describe values above and below zero. They also support coordinate thinking, where direction and sign both matter.
Open one card at a time, read the text together, and use the audio button when hearing the line once helps.
integer change
Count the change across zero carefully.
Example: The temperature dropped by 5 degrees.
number line movement
Rising means moving toward zero or into positive numbers.
Example: The diver rises 5 metres.
coordinate meaning
Read x first, then y.
Example: Negative x means left; positive y means above.
strategy
Visual models reduce integer mistakes.
Example: A quick sketch can make integer thinking clearer.
These next steps stay in the same stage so the child does not get sent backward.
Use ratios to compare quantities and unit rates to find the value for one item or one unit.
Read charts carefully and connect percentages to familiar fractions or out-of-100 thinking.
Recognize number patterns, write simple algebraic expressions, and solve one-step equations with understanding.
