Your future chefs will appreciate this comprehensive lesson where learners practice operations on fractions using pizza and soup analogies. Learners begin with a pizza analogy that requires the learners to multiply a whole...

See how design and geometry go hand in hand. The activity asks learners to use geometry to design a backyard garden given dimensions of each feature. Scholars work with ratios and scale to develop an accurate scale drawing that includes...

Presenting ... the gold standard for a lesson. Learners first investigate a task maximizing the area of a plot for gold prospecting. They then examine a set of sample student responses to evaluate their strengths and weaknesses.

As part of a study of geometric patterns, scholars complete an assessment task determining the number of tiles needed to cover a tabletop. They then evaluate provided sample responses to see different ways to solve the same...

Halfway through the module — the perfect time for an assessment. The 18th installment of a 36-part series is a mid-module assessment. Scholars provide evidence of understanding through various mathematical and contextual problems.

Learners explore patterns, identify patterns, and complete a variety of patterns. They view and discuss an online video and identify the different patterns from the film, then using a hundreds grid create an original pattern using their...

These improper fractions need to be renamed, and young mathematicians are guided through the process to simplify 36 of them here. They change each to a mixed number, sometimes simplifying further to get the fully reduced form. There are...

Your class members will feel confident in taking notes during your next lecture with this great note-taking worksheet, through which learners practice activating prior knowledge, recording key points, flagging...

These numbers have some personality! Are they rational or irrational? The lesson examines the definitions of rational and irrational numbers and shows examples of how to identify them. 

Seeing is believing. Given several bivariate data sets, learners make scatter plots using the online SeeIt program to visualize the correlation. To get a more complete picture of the topic, they research their own data set and perform an...

Don't discount how much your pupils understand percents! The 27th lesson in a series of 29 presents a problem to find the cost of a discounted outfit. Small groups determine either the original price or the discount received given the...

Your learners will appreciate this assessment of basic skill calculations that are prerequisite to Algebra1. Adding, subtracting, multiplying, and dividing procedures are addressed in conjunction with whole numbers, decimals, fractions,...

Where do those asymptotes come from? Learners graph, simplify, and solve rational functions in the fifth module of a 10-part series. Beginning with graphing, pupils determine the key characteristics of the graphs including an in-depth...

Maximizing resources is essential to productivity. Class members complete an activity to show how math can help in the process. Using a piece of construction paper, learners construct a box with the maximum volume. Ultimately, they...

In this quantitative data instructional activity, pupils compute measures of central tendency, draw vertical line diagrams, and compare collected data. This 23-page instructional activity contains approximately 100 multi-step problems....

Viewing this slide show prepares your chemistry scholars for chemical nomenclature. Specifically, binary hydrogen compounds and ternary compounds formed from oxyacids are dealt with. One highlight is a useful graphic organizer for naming...

In 1941 FDR spoke out on the events at Pearl Harbor. The class will get to analyze word choice,  word meaning, author's craft and structure by analyzing an actual draft of this speech. They will look critically at the words used,...

Does writing the name of a color in a different colored ink affect one's ability to read it? Scholars design an experiment to answer this question. They collect the data, analyze the statistics, and draw a conclusion based on...

How high can your pupils jump? Learners design an experiment to answer this question. After collecting the data, they create box plots and scatter plots to analyze the data. To finish the lesson plan, they use the data to...

Equip young campers with important survival knowledge with a set of engaging lessons. Teammates work together to complete three outdoor activities, which include building a shelter, starting a campfire, and finding directions in the...

Generating a system of shapes. Groups work together to create a number system using three different shapes as symbols. The groups should come up with the rules that generate all the possible permutations of the three shapes.

Help your class determine the types of pollutants coming from vehicle exhaust. Groups use an air quality monitor to determine the emissions from different vehicles, to gain knowledge about combustion energy, and to predict how the...

All chemical reactions require energy. To explore thermodynamics, classes read and discuss its laws, exothermic and endothermic reactions, enthalpy in many forms, calculate enthalpy problems, and use Hess' Law to calculate enthalpy of a...

Just how far off is the least squares line? Using a graphing calculator, individuals or pairs create residual plots in order to determine how well a best fit line models data. Three examples walk through the calculator procedure of...
