The national epidemic of opioid addiction is making its way into high school populations. Educate the students in your class about the ways prescription opioids can both block pain and deliver large amounts of dopamine that make it very...

Are you nuts? An engaging experiment burns nuts to find their kilocalories. Young chemists analyze at least two different types of nuts with their experimental results versus what is on the package. The resource offers a great lab...

In this same or different Easter theme worksheet, students look at pictures of Easter related items, circling those that are different from the other. A reference web site for additional activities is given.

Students rewrite word problems using the correct symbols. In this algebra instructional activity, students find the trigonometric identities and use them to solve problems. They write equations for the trigonometric ratios.

In this estimation worksheet, students solve a total of 6 word problems that involve rounding to a given place value and estimating.

Analyze the flight of a thrown ball. Learners determine the maximum height of a thrown ball and the time it takes to hit the ground given its initial speed. They continue to review different scenarios with different maximums or...

Play with paint and decide the ratio to make different shades of green. When mixing paint colors, your painters should decide which ratios make the same shade and what is needed to mix other ratios for a different shade of green. This is...

Math language? Set notation is used in mathematics to communicate a process and that the same process can be represented as computer code. The concept to the loop in computer code models the approach pupils take when creating a solution...

Don't let the resource hide from you. In the assessment task, young mathematicians solve problems involving chameleons that change color. Three different problems require individuals to apply parity in various situations.

How much material is in a bead? Class members utilize volume formulas to determine the amount of material in a bead. The goal of the assessment is to show that the amount of material left in a bead is the same for all beads with a...

Organizing data in a statistics class is often a challenge. A veteran statistics teacher shares data organization tips in a lesson resource. The instructor shows how to group data to link to individual calculators in a more efficient...

Adolescents love to shop, especially when an item is discounted. Here, shoppers only have a set amount of money to spend. Will they be able to make a purchase with the discount and tax added in? Percent discounts can be calculated...

A video and popcorn, just like being at the movies! Given the dimensions of two different cylinders, scholars decide which will hold the most popcorn. They find out if their calculations are correct with the provided solution video.

The problem seems simple: find the area of the equilateral triangle whose sides are each length 1. In fact, this same problem is solved in 8th grade, addressing a different Common Core standard, using the formula for area of a triangle...

Scholars first investigate relationships in the side lengths of 30°-60°-90° triangles and 45°-45°-90° triangles. This knowledge then helps them solve problems later in the lesson about special right triangles.

Investigate the proportional relationships of length, area, and volume. Learners use the dimensions of rectangular prisms to create ratios and proportions. They compare the different ratios to solve more advanced problems.

What number does 6 tens and 16 ones represent? How is it different from or similar to the number that 7 tens and 6 ones represent? This is the type of questions learners are asked to solve as a way to understand the concept of regrouping.

Four 4s represent the counting numbers. Pupils attempt to write equivalent expressions to as many counting numbers as possible using only four 4s. Scholars then determine whether the same feat is possible using only three 3s.

Mixtures, weighted percentages, and varying speeds make problem solving difficult. The resource give learners a strategy for tackling these types of problems effectively. 

What came first, pedestrian one or pedestrian two? Scholars consider a problem scenario in which two people walk at different rates at different times. They must decide who reaches a checkpoint first. Their answers are likely to surprise...

What does math have to do with a sore throat? When you mix water and salt you have a great review of how to represent proportional relationships by an equation or graph. Here the proportions of the mixtures may be different, but the...

Where in the world (or at least in the coordinate plane) is the third vertex? Given two coordinate points for the vertices of a triangle, individuals find the location of the third vertex. They read an account of fictional...

How do the area and perimeters of circles and squares compare? A clever video illustrates the change in the area of a circle and square while their total perimeter stays the same. The task is for learners to predict the point where the...

What can symmetry tell us about triangles? After looking at four examples, learners will come to realize that lines of symmetry are different for equilateral, isosceles, and scalene triangles. Use this guided practice activity as an...
