Students use this problem to develop spatial skills. As the students handle the shapes and join them together they strengthen their understanding of the attributes of shapes. This lesson also gives students the opportunity to make up...
Curated OER
Colourful Jerseys
Students form a repeating pattern using shoe colour (eg., white, brown, white, brown). Without knowing what pattern they are using ask the students to join the line if they think that they could be the 5th member of the pattern. Ask them...
Curated OER
Buttons and Bears
Students read the problem and then identify the important information in the problem and highlight. They then brainstorm for ways to solve the problem by drawing a picture and working in pairs.
Curated OER
Figure This!
Second graders explore the concept of inequalities. They use the mathematical symbols =, <, > to show relationships among numbers. Students devise and use problem solving strategies to explore the situation.
Curated OER
Three Coins on a Table
Students discuss the subject of coins and heads and tails. They work in groups to solve Fran's problem concentrating on the fact that the coins are in a row. Any group that finishes early can try the Extension problem.

My Dogs
Students use the properties of multiplication to solve problems. They recall the basic multiplication facts as well as write and solve problems that involve whole numbers.
Curated OER
The Fathers' Day Card
Students subtract using decimals and find half of a decimal number. They write and solve problems which involve decimals and which require a choice of one or more of the four arithmetic operations.
Curated OER
Pocket Money
Students discover that the mathematics behind this question is a comparison of the rate at which adding a fixed number increases the total compared to continual doubling of a number. In fact no matter what whole numbers you start with,...
