Partitioning Shapes into Equal Shares
Students will partition circles and rectangles into two, three, or four equal shares, describing the shares using words like halves, thirds, and fourths.
Key Questions
- Justify why two halves of a shape must be equal in size.
- Construct different ways to partition a rectangle into four equal shares.
- Compare partitioning a circle into halves versus partitioning it into thirds.
Ontario Curriculum Expectations
About This Topic
Weather Patterns focuses on observing, measuring, and predicting the atmospheric conditions in our local environment. In the Ontario Grade 2 curriculum, students learn to use simple tools like thermometers and wind vanes to collect data. They explore how weather changes day-to-day and seasonally, and how these patterns affect the lives of humans, plants, and animals. This unit encourages students to become 'citizen scientists' by recording their own observations over time.
Understanding weather patterns helps students prepare for their day and understand the broader climate of Ontario. This topic is perfectly suited for station rotations and collaborative data analysis. When students work together to track temperature or wind direction, they are practicing essential math and science skills. Active participation in daily weather tracking turns a routine task into a meaningful investigation of the world around them.
Active Learning Ideas
Stations Rotation: Weather Tools
Set up stations with different tools: a thermometer in warm/cold water, a wind vane with a fan, and a rain gauge. Students practice reading the tools and recording the 'weather' at each station.
Inquiry Circle: Seasonal Sort
Groups are given a set of photos showing different weather conditions, clothing, and animal behaviors. They must sort them into the four seasons of Ontario and explain how the weather pattern in each season influences the choices we make.
Think-Pair-Share: The Morning Forecast
Students look at the sky and the current temperature. They think about what the weather might be like by recess, pair up to share their 'forecast' and reasoning, and then check the actual weather later in the day.
Watch Out for These Misconceptions
Common MisconceptionThe sun 'goes away' when it is cloudy.
What to Teach Instead
Students often think the sun is gone on grey days. Use a flashlight and a piece of thin fabric to show that the light is still there, just blocked by the clouds, helping them understand that the sun is always present above the weather.
Common MisconceptionTemperature only changes when the seasons change.
What to Teach Instead
Children may not notice daily fluctuations. By keeping a daily weather log for a week, students can see that temperature changes from morning to afternoon and day to day, even within the same season.
