Curated OER
A thousand seconds
Pupils use seconds, minutes, and hours. They then discuss the size of a thousand. After that they read time in digital or analogue form.
Curated OER
Parking Meters
Third graders are introduced to the problem with a short discussion about parking. They then solve with a partner. As they work ask questions that focus on the strategies they are using to make the calculations.
