Subtraction of Numbers to 20
Investigate subtraction of positive and negative integers, fractions, and decimals, using various methods and understanding 'subtracting a negative'.
Key Questions
- What does it mean to take away some objects from a group?
- How can you use counters or a number line to find the answer to a subtraction?
- Can you tell a take-away story using objects from the classroom?

About This Topic
Warm and Cool Landscapes introduces the concept of color temperature and its effect on the viewer's emotions. In 1st Class, students begin to categorize colors into 'warm' (reds, oranges, yellows) and 'cool' (blues, greens, purples). This topic links the Visual Arts curriculum with Geography, as students use these colors to depict different climates, seasons, and times of day.
By exploring how a blue forest feels different from a red desert, students learn to use color as a narrative tool. This topic is perfectly suited for comparative activities and collaborative critiques. When students work together to categorize images or debate which colors best represent a 'stormy night' versus a 'sunny morning,' they develop a deeper understanding of how artists manipulate mood.
Active Learning Ideas
Formal Debate: Hot vs. Cold
The teacher displays a painting of a sunset. Half the class argues why it feels 'warm,' while the other half looks for 'cool' shadows. They must use specific color names to support their points.
Inquiry Circle: Seasonal Sorting
Small groups are given a pile of landscape photos. They must sort them into 'Warm' and 'Cool' piles, then explain to the class which colors helped them decide for the trickiest photos.
Think-Pair-Share: The Temperature of a Story
Students are given a short story prompt (e.g., 'A dragon in a volcano' or 'A penguin on an iceberg'). They discuss with a partner which three colors they would use to paint that scene and why.
Watch Out for These Misconceptions
Common MisconceptionGreen is always a cool color.
What to Teach Instead
Students often put all greens in the 'cool' box. By comparing a lime green (yellow-heavy) to a forest green (blue-heavy), they learn that colors can sit on a spectrum of temperature.
Common MisconceptionLandscapes must always have a blue sky and green grass.
What to Teach Instead
Children often fall into 'symbolic' drawing. Looking at diverse landscapes (like an orange desert or a purple twilight) through gallery walks helps break these habits.
