Challenge your class to use straight lines when estimating the length of a curve. An engaging interactive allows individuals to place line segments one after another along the arc. Learners determine that the more lines used, the better...

Learners estimate and determine the number of cents (pennies) that are needed to equal the mass of a variety of common objects. They develop a process for measuring and explore concepts related to units of measurement.

Using the provided blank face template, learners of any age draw to learn how to create proper facial proportions. This lesson focuses on two dimensional facial proportions, how to estimate those proportions, and drawing techniques. If...

Middle schoolers practice skills involving statistics and probability by making predictions on number of each color candy in one pound bag of M&Ms. They record both guesses and actual quantities, calculate percentages, and create bar...

Upper grade and middle school learners problem solve and calculate the answers to twenty various word problems involving multiplication, and a bar graph.

In a cross-curricular measurement and literacy lesson, your class will identify and compare cooking measurement instruments. They read a recipe and sequence a set of similar instructions in which the steps have been mixed up....

Help your class make sense of quantities and their relationships. Given is the product of two numbers. It is up to your number crunchers to think about the quantitative relationship when the product is one-tenth or ten times the product...

How accurate is data collected from a sample? Learners answer this question using a simulation to model data collected from a sample population. They analyze the data to understand the variability in the results.

Is 0.56 stronger than -0.78? Interpret the correlation coefficient as the strength and direction of a linear relationship between two variables. An algebra lesson introduces the correlation coefficient by estimating and then...

Financial literacy skills and exponential models are connected by the compound interest formula in this task centered on inflation calculations. Collaborative learners get experience collecting data from the given websites and exploring...

Scholars have an opportunity to use their geometric modeling skills. Pupils determine a reasonable estimate of the number of string beans that would fill the average human body.

Students estimate the distance of student's broad jumps. This activity can take place in the block center with a small group of students. They are explained that they are going to jump from a starting point (marked with the masking...

Youngsters count, classify, and estimate quantities using buttons after a read aloud of The Button Box by Margarette S. Reid. They discuss the difference between guessing and estimating. Based on an experiment, they predict the...

In this science worksheet, students create a race track and mark each distance as stated. Then they perform each task and record the time it takes them for each. Students also record their data from the experiment into the chart...

There is more than one way to measure an amount, as learners discover by applying multiple measurement tools in these activities. Centimeter cubes, cylinders, beakers, and measuring cups are used to find the volume of regular and...

Explore all things decimal in this thorough series of introduction activities. Including scripting for the teacher and detailed descriptions and examples, the plan begins by reviewing the basics of place value and writing fractions as...

Students use their feet to measure distance between themselves and a tree trunk.  In this distance lesson, students use the number of steps, and string to measure distances and height of the tree.  Students can get the tree...

Investigate the length of various objects in metrics! In this measurement lesson, 2nd graders estimate and find the length of objects in the classroom using centimeters.

How fast does water cool? First fifth graders will draw a line on a graph that predicts how fast they think water can cool from boiling. Then they plot the actual data on the same graph to see if their estimate was correct.

Trying to get your class to think of decimals as fractions and vice versa can lead to interesting discussions. After all, we can usually understand quickly that 1/4 is .25 but why is 1/7 not so easy to convert? This activity looks...

Emerging statisticians develop the ability to make inferences from sample data while also working on proportional relationships in general. Here, young learners examine samples for bias, and then use random samples to make...

Your task today: count all the trees on a tree farm. To complete the assignment, learners first estimate the number of trees on a tree farm using random sampling. To improve their own response they then evaluate provided...

A middle school test contains two 40-minute sections covering material through algebra. All questions involve applied problem solving or mathematical analysis.
