Working in small groups students develop three alternative boat designs. They discuss the rationale for the type of hull, propeller, location of ballast, and type of building material used in their design. They build their boat.

Scale up your lessons with a performance task. Young data analysts work through an assessment task on scaled bar graphs. They answer questions about a given scaled bar graph on favorite colors, analyze a bar graph to see if it matches...

In this scale image worksheet, students use an image taken by the LRO satellite of Mare Nubium to determine the scale of the image, the diameter of the smallest crater and a comparison scale drawing of a house.

Find the percent of the population that meets the criteria. The 17th segment of a 20-part unit presents problems that involve percents of a population. Pupils use tape diagrams to create equations to find the percents of subgroups...

In this nebula worksheet, students read about the Crab Nebula and calculate the average speed of the expanding gas. They determine the size of the smallest clumps of gas and they draw the diameter of the solar system to scale.

In this maps worksheet, students redraw a map to make it more accurate and drawn to scale in the space given. Students draw 1 map and answer 2 questions.

Ninth graders participate in a instructional activity focused on the concept of basic statistics. They find the mean, median, and mode of different data sets. More advanced students could practice creating a bell curve from the data.

Students collect and record data. In this collecting and recording data lesson, students collect data and record that data using frequency tables which include the x and y axis.

Students interpret data from graphs. In this range and mode lesson, students review a tally chart, pictograph and bar graph. Students use these graphs to calculate the range and mode of each set of data.

Students explore transformations.  In this mathematical transformations lesson, students define quadrilaterals, convert centimeters to meters, and complete a transformations worksheet.

Sixth graders estimate surface area of a pond using a random number table.

Fe, phi, fo, fum. This activity leads pairs to find the ratio of consecutive terms of the Fibonacci sequence. The pairs find that the Fibonacci sequence can be found in many places. A discussion with the class shows that the ratios...

In this probability worksheet, students determine the probability of events using a probability scale and write events with only two outcomes. In this short answer worksheet, students write answers to eleven questions.

In this math worksheet, middle schoolers look for the actual values for the measurements of distance. The answers are found on page three.

Students understand that a spreadsheet can be used to find the best scale to use in a model. They place the distances of the planets of the solar system to the Sun in one column of the spreadsheet. Students try different scales so that...

Ninth graders explore the concept of ratios. In this ratio lesson, 9th graders construct a to scale time line that starts at the beginning of time. Students determine the correct placement of big events in time such as when the dinosaurs...

Students explore numbers, computation, ratios, proportions, probabilities, statistics, and money in this six lessons unit. Practical applications in the real world are emphasized through an interactive approach to math in these lessons.

Students draw conclusions and make conjectures given a specific scenario. In this geometry instructional activity, students model real life scenarios using properties of triangles. They model number facts and explain why the outcome is...

High schoolers think about several of the concepts from fractals, including recursion and self similarity. They use mathematical concepts of line segments, perimeter, area and infinity are used, and skill at pattern recognition is...

Fifth graders explore real-life situations of area and perimeter. They develop a list of real-life applications of area and perimeter, select a situation, and write a step-by-step procedure and diagram on graph paper for solving the...

An engaging lesson which has elementary learners measure weight to the nearest pound and construct and interpret a bar graph! They measure length using non-standard units and determine area using square tiles. Pupils round their birth...

Explore mathematics by analyzing images. As they view pictures on the SMART Board, individuals must write corresponding algebraic equations. They utilize models to visualize the math expressions.

How many visual models can be used to show multiplication? Three basic kinds of models can be used to represent and explain the equation 4 x (9 + 2).  The commentary section provides description and graphics to explain the set...
