We know that sample data varies — it's time to quantify that variability! After calculating a sample mean, pupils calculate the margin of error. They repeat the process with a greater number of sample means and compare the results.

You may be able to see patterns visually, but mathematics quantifies them. Here learners find correlation in scatterplots and write equations to represent that relationship. They fit a line to the data, find two points on the line, and...

Students explore statistics by completing a graphing activity. In this data analysis lesson, students define a list of mathematical vocabulary terms before unpacking a box of raisins. Students utilize the raisins to plot data on a line...

Pupils investigate poverty using graphs. In this algebra lesson, students collect data on the effects of poverty and use different rules to analyze the data. They graph and use the trapezoid rule to interpret the data.

Sixth graders explore using inverse operations to solve decimal and fraction problems. In this decimal and fraction instructional activity, 6th graders prepare ribbon for a part and need to cut it in equal lengths. Students analyze the...

Fifth graders examine patterns and relate to equations to solve math problems.  In this patterns lesson plan, 5th graders diagram, graph, use models and use tables to solve equations for real world problems.

Here is a (great) lesson on using parentheses! The task requires the expression of ages using algebraic expressions, including the distributive property. Pupils use their expressions to determine the individual ages.

Learners explore the concept of probability.  In this probability lesson, students use area to determine probability.  Learners use charts and spinners to help determine the probability of events such as flipping a coin or...

Learners explore multiplying fractions and their relationship to parts of a whole. They draw and shade fractional parts to show parts of a whole and fractional parts of a fraction. Pupils also use an Internet site for interactive...

Use paper strips or models to relate division problems to division of fraction problems. Since the materials can be broken up, it helps them to show how they can complete repeated subtraction with fractions and not just whole numbers.
