The way you use statistics can tell different stories about the same set of data. Here, learners use sets of data to determine which person sends the most text messages. They use random sampling to collect their data and calculate a...

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.

Is it possible to add infinitely long decimals? As pupils complete the examples in the ninth lesson plan of this 25-part series, they determine that adding these decimals cannot be done without error. Their task is then to determine the...

Students describe the differences between an estimate and a guess. They create reasonable estimates based on comparison and activities. Students explain how estimation is helpful in showing the relative size on a scale. They also...

Students discover the actual size and weight of many insects and animals. For this biology lesson, students investigate animals and insects to determine their actual weight and size. In groups, students create an animal or insect of...

Students investigate how size affects large and small animals differently. In this animal lesson plan, students determine how size affects different animals by constructing their own animal out of marshmallows. Once students create...

Students explore early hominid evolution as they analyze bones that share characteristics of both apes and humans. Students compare and contrast key skeletal differences between chimpanzees and humans. In groups, they sort and group a...

Students examine genocidal events throughout history. Using the internet, they research these events and compare and contrast them with the Holocaust. They analyze the amount of inhumanity towards others throughout history. In groups,...

Students practice counting and comparing objects.  In this math lesson, students view a Count on It! episode. Students examine the value of what they are counting.  Students estimate number in groups of items.  Students...

In this comparing plant and animal cell instructional activity, students use a microscope to observe cheek cells and onion cells. They compare their observations and answer 3 questions about their discoveries.

Although this is a science instructional activity, it can be adapted to help meet Common Core standards in math as well. Starting scientists describe physical properties of objects and explore three forms of water. To address the Common...

Instruct your class on how to put together a sentence in Spanish. The resource covers the different parts of speech, showing how the Spanish version of each sentence compares with the English version. While there are no procedures...

Geometry.... sweet! Using sugar cubes, learners build rectangular prisms of different sizes and shapes. They glue them together and assess volume. Then they color the outer sides to visualize and compute surface area. To make a visceral...

First graders compare triangle sizes, square sizes, and lengths. They use manipulatives of three varied sized triangles, squares, and strips to measure and compare relative size and length.

In this comparing lengths worksheet, students study the illustrated pictures in each row. Students then circle the shortest picture in each row.

What was one of the big takeaways from 2009? By reviewing the released AP® Calculus free-response questions, pupils and teachers realize that performing mathematics is not all there is to doing well on the exam. Several items require...

In this finding the smallest apple worksheet, young scholars look at the pictures in four boxes, then color the smallest apple in each one.

Students compare, resize, and check various shapes by size using a comparison mat from the MathKeys program. Working in pairs, they place three similar shapes on the screen and state which is the largest and smallest in area. They also...

Class members study the size of classmates' feet and perform a statistical analysis of their data. They solve for central tendencies, quartiles, and spread for the entire group as well as subgroups. They then write a conclusion based on...

Engage in a shady activity to practice measurement techniques. Classes venture outside to collect measurements of various trees, using different strategies to measure the height, trunk circumference, width, and crown size. Then they...

Young scientists demonstrate how to move objects. In this fine motor lesson plan, students use various objects such as dice, erasers, and soft balls and move them using the proper device.

Teenagers face many temptations, and just saying "No!" can be very difficult. Here's a instructional activity that provides some help. Learners use a Venn diagram to compare and contrast excerpts from The Odyssey, Tennyson's "The...

Space science stars journey through our night sky and take virtual photos of galaxies to investigate simple random samples. Higher math is used to analyze the data collected. Copy the evaluation/assessment questions onto a handout...

A mouse can fall from large heights without injury! Air resistance is a large influence on small falling objects. In an exploratory lesson, young scholars build a raindrop bottle to compare the falling rate of different-sized objects.
