In this math worksheet, young scholars are given 7 problems in which they differentiate, figure rate of change, determine value, and prove formulas.

Part of as assessment series, the activity follows the activity Molly's Run to practice ratios and dividing with fractions. Different solution options are given for your learners' preference. The commentary explains how...

Take your class on a North American adventure with a currency conversion problem. Pupils are asked to change US dollars into Canadian dollars and then to Mexican pesos. The commentary includes two solutions, converting by unit rates and...

The idea in the resource is to understand the connections between proportional relationships, lines, and linear equations. To stay within the context of the standard, skip the part of the resource that solves with unit rates. Instead,...

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...

Learners name the main parts of the heart and what events occur there. They write a reaction that contains complete sentences, and uses proper spelling and grammar, after viewing a video. Students define the following terms: contraction,...

Put economics and currency exchange rates into a real-world application kids can understand. They'll compare bus fares from various cities around the world. Each child selects three international cities to research. They determine the...

Examine ratios and proportions in several real-world scenarios. Children will calculate unit rates, work with proportions and percentages as they plan a party, purchase produce, and take a tally. This lesson plan recommends five...

This is a great exercise in graphing proportional quantities to interpret the unit rate as the slope of a graph. It is not easy for learners to understand what a unit rate is. When it is presented as the slope of a linear line graph,...

How many boys are in the class? Here is an introductory exercise describing ratios. The commentary shows different ways learners can approach the problem, using a tape diagram of boys to girls and using a table. The activity includes...

Using rates from a rental car company, young mathematicians graph data, explore linear relationships, and discuss the role of slope and the y-intercept. This lesson allows for the discussion of independent and dependent variables, as...

Students explore how to calculate rates. In this rate calculation lesson, students watch a CyberSquad video and then calculate positive, negative, and zero rates from graphs.

When was the last time your class saw a catalyst in action? Chemistry scholars observe an activated complex during an engaging experiment. Through both color change and evolution of a gas, individuals gain insight into the...

Algebra learners like this resource because it is easy to understand and it relates to their lives. Whether you are starting a new workout routine, or just climbing the stairs, your heart rate increases and decreases throughout the day....

Students complete an experiment with Alka-Seltzer and reaction rates. They control the rate in which gases are allowed to escape. They test their predictions and observe what happens during the experiment.

Use a KWL chart and discussion to explore the concept behind loans with interest based on percentage rates. Learners examine different types of interest, the history of interest loans and calculate the costs of a loan over a ten-year...

Seventh-graders solve 20 various types of problems related to ratio and rate. They write ratios in simplest form for each given statement, to compare the area of two figures, and write two ratios equivalent to each ratio. Pupils express...

How quickly does a plant transpire? Learners explore this question through measuring water uptake with a potometer. They time the movement of a bubble a set distance to understand the motion and rate of speed.

Practice consumer mathematics through by investigating home mortgages. Budding economists find the interest rates for 30-year and 15-year loans and calculate the estimated monthly payments. They use their data to compare periods of time...

Plant respiration can be a difficult concept for young biologists to grasp; with a hands-on lab, learners can collect and graph data, then calculate the metabolism rate for the plants they studied. If you do not have a respirometer,...

Your class will be very interested in the results of this activity. How long does it take a MP3 and video game player to charge?  Sam only has an hour and the MP3 player only has 40% of its battery life left. Plus, his video player...

How much money is enough money? Future wage earners explore the minimum hourly wage and then use it to calculate monthly and yearly earnings. They use an interactive to consider living costs and determine whether earning a minimum wage...

Sometimes you just want to know the cost of one apple. A fun interactive lets learners explore the unit costs of fruits, vegetables, and candy. It shows how ratios to express ratios symbolically and on a double number line.

Students examine coins from around the world and write down their observations. As a class, they discuss the types of symbols used on the coins from different countries and locate the country on a map. To end the lesson, they calculate...
