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.

Communicating results is just as important as getting results! Learners create a poster to highlight their findings in the experiment conducted in the previous lesson plan in a 30-part series. The resource provides specific criteria and...

How does a bank make money? That is the question at the based of a lesson that explores the methods banks use to calculate interest. Groups compare the linear simple interest pattern with the exponential compound interest pattern. 

Thank goodness we have calculators to compute logarithms. Pupils use calculators to create logarithmic tables to estimate values and use these tables to discover patterns (properties). The second half of the lesson plan has scholars use...

Use the resource to teach methods for solving exponential equations. Scholars solve exponential equations using logarithms in the twenty-fifth installment of a 35-part module. Equations of the form ab^(ct) = d and f(x) = g(x) are...

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...

Could you determine longitude based on measuring time? Early explorers used a longitude clock to do just that. Scholars learn about early exploration and the importance of the invention of the clock. Then pupils build their own longitude...

Start your engines! Small groups collect data from websites pertaining to the Indianapolis 500 in order to determine average speed per lap and miles in each lap. The activity requires prior knowledge of the the formula d=rt.

Help your math class understand variables. This activity is for a visual learner. They will use weights and a balance scale to show how the sides of an equation are equal. Worksheet is included.

Go on a moon mining expedition from the safety of your classroom with this space exploration simulation. Using simple models of the moon's surface prepared ahead of time by the teacher, young scientists are challenged with locating and...

Fifth graders look at actual sunrise and sunset times for their hometown to determine a pattern in the amount of daylight. They collect their data in Excel and create a chart to help them identify the pattern, then write an explanation...

Arithmetic apprentices practice problem solving and multiplication with a lift-the-flap pair of reproducibles. In this Halloween mathematics lesson, math monsters practice multiplication by making candy corn calculations. They practice...

Working independently or in teams, your class practices connecting graphs, formulas and words. This lesson includes a guided discussion about distance vs. time graphs and looking at how velocity changes over time.  

It's time for your young artists to shine! Learners examine images to determine possible similarity transformations. They then provide a sequence of transformations that map one image to the next, or give an explanation why it is...

Time to put it all together! Building on the concepts learned in the previous lessons in this series, learners apply the Remainder Theorem to finding zeros of a polynomial function. They graph from a function and write a function from...

Time for statistics and learning to overlap! Learners examine Venn Diagrams as a means to organize data. They then use the diagrams to calculate simple and compound probabilities.

Time to experiment with mathematics! Learners study experimental design and how randomization applies. They emphasize the difference between random selection and random assignment and how both are important to the validation of the...

Would your ideal science lab be filled with bubbling beakers and zapping Tesla coils? Or would it contain state-of-the-art computer technology and data analysis? Dream big with an innovative lesson that connects math and language...

Statements often have multiple interpretations — but not these inequality statements. Scholars compare rational numbers and write inequality statements symbolically. The lesson includes problems that require comparing three numbers.

Four quadrants, four times the fun. Future mathematicians learn the terminology associated with the coordinate plane and how to plot points in all four quadrants. A worksheet tests their understanding of the material in the 16th...

Young scholars explain why the number of appliances used today differs greatly from the number used previously. They construct a bar graph to show changes in appliance use over a period of time. They also list appliances that could be...

Students explore things that are their size, literally. In this early childhood lesson plan, students use their bodies for measuring and comparing sizes as they work in pairs to complete the activity.

Third graders plan for a garden. In this garden planning lesson, 3rd graders investigate the use of a grid to accurately map out and plan for a vegetable garden. Students predict the space requirements for different vegetables.

Students investigate the use of hydroponic gardening on the world food supply. In this hydroponic gardening activity, students make a garden out of a soda bottle, grow a cilantro plant, and compare hydroponics with regular gardening...
