Young scholars work with circles, angles and estimating angles in the night sky. In this circles and angles lesson, students practice measuring a degree using the circumference of a circle and apply the degree to determine a way to use...

The laws of exponents are written on a handy reference sheet. Note that since this worksheet was written in the UK, powers or exponents are also called indices (singular: index). If this does not pose a problem for you, the concepts and...

Numbers can take many forms. Learners practice translating one form to another in this place-value worksheet. They start with a word-form number and choose which of six three-digit numbers is less than (the worksheet uses the term below,...

Fractions should be visual for beginners; give scholars a few different approaches through these five problems. First, they examine two shapes with shaded sections, writing a fraction to represent the shaded portion. Next, mathematicians...

Using fractions as their artistic guide, learners color in parts of five shape images. Each image is segmented based on the denominator, so scholars simply need to apply the numerator to know how much to color. None of these are mixed...

Apply area calculations to everyday situations using these three word problems. Mathematicians must pay attention to the needs of each space, determining the largest or smallest area of several options. Consider expanding on this by...

Combine numbers and pre-reading by counting the words in a sentence. Kindergartners  begin by counting objects in the room, putting a counter down for each number. Do this a few times to get them confident with the skill before...

If you need some creative ways to teach the order of operations, use a series of activities that focus on properties. Each instructional activity uses different materials and works as a stand-alone activity, or can build upon the...

Use a triangle area formula that works when the height is unknown. The eighth installment in a 16-part series on trigonometry revisits the trigonometric triangle area formula that previously was shown to work with the acute triangles....

Practice with unit rates, proportions, and ratios when Carlos purchases an amount of bananas. Learners must interpret a graph to decide whether points on the same line represent similar proportional relationships. Use with lesson plans...

Give children credit where credit is due with this classroom management system. Providing each student with their very own charge card, they are able to gain credit for being respectful and responsible and...

Have a hopping good time teaching your class how to collect and graph data with this fun activity-based lesson series. Using the provided data taken from a frog jumping contest, children first work together...

Bridge the gap between mathematics and Career Technical Education. Pupils research the cost associated with building storage sheds and analyze possible profit. They build scale models and determine if building and selling the sheds is a...

Let's save some money! High schoolers investigate different options for price reductions. They then determine the best and worst sale from a list of options.

Don't think negatively about exponents. Young mathematicians dissect a fictional conversation between pupils trying to evaluate an expression with a negative exponent. This allows them to understand the meaning of negative exponents.

Airline mechanics must be precise, or the consequences could be deadly. Their target ranges alter with changes in temperature and pressure. When preparing an airplane for flight, you must read a maintenance graph. The second lesson of...

Leave no student behind with this differentiated geometry unit on perimeter and area. Over the course of five lessons, young mathematicians explore these foundational concepts through a series of self-selected hands-on activities and...

What do Sherlock Holmes and geometry have in common? Why, it is a matter of deductive reasoning as the class learns how to justify each step of a problem. Pupils then present a known fact to ensure that their decision is correct.

Add visual representation to teaching place value with a magnitude model. Using adding machine tape, pupils build a linear place value strip from 1 to 100.

Inscribed angles are central to the instructional activity. Young mathematicians build upon concepts learned in the previous instructional activity and formalize the Inscribed Angle Theorem relating inscribed and central angles. The...

Increase your sample and increase your accuracy! Scholars complete an activity that compares sample size to variability in results. Learners realize that the greater the sample size, the smaller the range in the distribution of sample...

It takes a lot of planning to achieve a random result! Learners compare results of random assignment, and conclude that random assignment allows results to be attributed to chance. They also realize the set of random means...

Hop into a resource on Beer's Law. A PowerPoint presentation introduces Beer's law as part of calculating bone density from X-ray images in the sixth lesson in the series of seven. Individuals work on practice problems with this law and...

This can be used as a critical thinking exercise in congruence or as a teaching tool when first introducing the concept. Four octagons are arranged in such a way that a square is formed in the middle. With this information, geometry...
