In this reaction rates worksheet, students solve eight multiple choice problems about chemical reactions and their rates. They determine what species would slow reactions, they apply concepts of activation energy to reactions, they...

Students investigate the rate of a chemical reaction. In this rate of reactions lesson plan, students use an electronic balance to measure the change in mass of a chemical reaction between hydrochloric acid and calcium carbonate. They...

In this unit conversion activity, students solve 4 problems given a list of conversion factors for units of energy, power and flux.

Young scholars study reaction rates, what determines how fast a reaction happens and how the chemical changes occur.  For this reactions lesson students complete a lab where they use Alka-Seltzer to observe reaction rate and create...

Students solve problems using ratios and proportions. In this algebra lesson, students identify the unit rate and convert between fractions and decimals. They create graphs from their data.

Seventh graders write with a pencil the conversions of teacher given unit rates with 90% accuracy after being led through several similar examples. They are quizzed on unit ratios after completing their homework assignments.

The votes are in and your mathematicians are going to calculate how many votes each candidate received. Three different solution choices are given, depending on which method is taught. Have your learners set up a table, compute parts, or...

Save pennies on your peanuts. Scholars first examine a picture of a supermarket display showing salted peanuts sold by the pound and by the bag. They apply the idea of unit rate to determine which is cheaper.

Pupils demonstrate an understanding of price-per-unit mathematics. In this computation lesson, learners accurately figure the unit price of grocery items. They create a chart and record the item, the price, the size and the cost per item.

What is an Egyptian Fraction? Print this sheet as a bell-ringer activity. Budding mathematicians solve three short answer problems. They write three fractions as unit fractions so that the numerator is one and the sum is equal to the...

Sixth graders investigate unit pricing to find which cup of coffee is a better buy. They use ratio and proportions to solve problems involving a change of scale in drawings, maps, recipes, etc. Students determine the unit cost of items...

The concept of slope gets an approachable, yet theoretical, treatment in a comprehensive algebra lesson. The use of functional notation and problem-solving techniques keep the material rigorous, but detailed teaching notes and lots of...

If mathematicians know the secret to compound interest, why aren't more of them rich? Young mathematicians explore compound interest with exponential functions in the twenty-seventh installment of a 35-part module. They calculate future...

After calculating election votes, your learners must determine how many votes the winner, John, got above 50%. This multi-step problem encourages them to think in a deeper way about what the question is asking them to find. Use with...

In this rates worksheet, high schoolers solve 10 multiple choice problems. Students find the unit price of an item to determine the best buy.

In this unit fractions worksheet, 2nd graders utilize fraction strips to determine if 4 unit fractions being compared should be separated by the signs < or >.

Help learners determine the rate of change for the temperature of sand. They will collect data on the temperature of wet and dry sand over time with a heat lamp overhead. Then make a scatter plot of the data and find a linear model to...

How much land does a parcel hold? How much fertilizer does it take for a field of corn? Pupils answer these questions and more as they apply ratio reasoning and unit analysis. 

Students recognize different consumer products, found in and around the home, that have reactive or denaturing properties when used together. They explore chemical and physical properties of each product by identifying chemical formulas...

Fifth and sixth graders practice working in pairs to determine whether they can walk with constant speed. They test themselves, collect their data, draw graphs with their data collected, manipulate the data, and then draw conclusions...
