Students collect data in the field and analyze it in class using tables and graphs to determine how many observations of a phenomenon are necessary to draw valid conclusions.

Third graders discuss discounts and walk around classroom labeled with lots of discounted merchandise. They complete a worksheet converting original prices to new bargain prices.

Students collect sunflower heads from their community garden. They estimate its seed count using different strategies. They graph their estimations on a graph and use calculators to find the actual total.

Students estimate the time it takes for an ice cube to melt completely.

Students explore mathematical problem solving. Given a case problem, students write a rule to solve problems involving decimal multiplication and division. They invent problems, share them with the class, and solve other student's...

Young scholars explore the concept of experimental and theoretical probability. In this experimental and theoretical probability instructional activity, students collect data by conducting a survey of their classmates. Young scholars...

Students take turns reading the electric meter six times a day at regularly scheduled intervals. They figure out the amount of electricity used and then determine the total cost of electricity for the week.

Students place two plane mirrors at different angles to experiment with reflection. They make kaleidoscopes and periscopes.

Students use seconds, minutes, and hours. They then discuss the size of a thousand. After that they read time in digital or analogue form.

Second graders discuss experiences of watching a rocket launch either on television or in person before making paper rockets. They make and color rockets which they attempt to launch using a strong breath blown through a straw at the...

Students practice data collection skills by observing common bugs found in their local environment. Once the data is collected they complete data sheets to compare, contrast, sort, and classify the insects. The lesson includes...

Third graders practice working out a hidden number on a calculator via number sequence in the advanced additive stage six. They assess number sequence to unveil a mystery number that has been entered onto a calculator and then switch...

Second graders practice measuring and estimating the length of two objects. They answer questions related to these topics and then work together in parts to complete a worksheet.

Students compare different habitats based on satellite imagery. They identify land features in the satellite imagery.

Students explore the size of a kilometer and the time it takes to cover this distance. They develop a concept of a km. They measure a distance of 1 km and the time taken to cover it.

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...

Learners 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...

Students and teacher talk about arrays of numbers like the ones in A Square of Circles. They check to see that the rows all have the same sum; that the columns all have the same sum; and that the diagonals have the same sum.

Students generate patterns from a structured problem, finding a rule for the general term, and expresses it in words and symbols. They then devise and use problem solving strategies to explore situations mathematically.

Students use equations to represent practical situations. They solve linear equations and quadratic equations. The use of problem solving strategies is also developed.

Eighth graders find connections between numbers in a table; use Pythagoras' theorem in a general algebraic form; and measure accurately from a scale drawing to find a method that might enable the helicopter to land inside a rectangular...

Students try some new exercises involving probability. These are, first of all, that the probability of getting a given total when two dice are rolled is equal to the number of possible ways of getting that total, divided by 36 (the...

Students write letters to town officials and local businesses asking for favorite dessert recipes. They tabulate their responses in a spreadsheet. Students turn their survey results into colorful graphs.

Young scholars investigate data of minimum and maximum weather temperatures over the period of one week. They answer guided questions in order to establish comprehension of interpreting the data.
