Young scholars add integers and use counters to create a visual. In this algebra lesson, students work in pairs as they use the computer to add integers. They complete an assessment on adding integers at the end of the activity.

I really like this clever lesson on using peanuts to help facilitate the learning of addition and subtraction for your young mathematicians. Youngsters use peanuts as "counters" for a variety of math problems that include greater than...

Second graders explore estimation and place value. In this place value lesson, 2nd graders estimate and construct numbers while working with spider activities. Students use addition and subtraction to compare estimates. Resources and...

Students use the zero principle to add integers. In this algebra lesson, students add positive and negative integers verifying the zero principle. They use manipulatives to help them see how opposites can cancel each other out.

Introduce young mathematicians to concepts of financial literacy with this open-ended word problem. With seven dollars to spend during field day and given a list of available items and their prices, children must determine how they want...

Using a real-world example, this problem illustrates the thought process that learners need to engage in to understand adding mixed numbers with common denominators. First by looking at estimation, and then by drawing models that...

Chemists consider a situation in which an ethanol producer needs to determine how much to add to t-butanol to prevent freezing during transport. They work in the laboratory to obtain the freezing point depression constant for the...

Advanced chemistry classes compare the polymerization of styrene using two different initators: benzoyl peroxide and aluminum chloride. Once they synthesize polystyrene, they compare the two producet for melting point and density. There...

First graders work with partners, using cubes to make addition sentences. In this math lesson, 1st graders separate cubes into 2 parts and discuss the relationship to addition sentences. Students practice separating cubes. Students make...

Students explore math functions by completing one-step problems. For this addition lesson, students utilize pencil and paper before completing practice addition problems which they examine with their teachers. Students utilize complete...

Pupils solve integers using addition. In this algebra lesson, students add integers using counters. They define and label patterns created by integer operations.

Students discover the significance of positive and negative numbers when working with money. In this addition and money lesson, students connect positive and negative numbers to money, solve practical examples together, and practice the...

Students add up the different angles using the angle addition postulate. In this geometry lesson, students differentiate between interior and exterior angles. They calculate the different angles for triangles and use proof to show their...

In a hypothetical scenario, food chemists use titration to concoct a brine solution for producing the crunchiest pickles. They also analyze store-bought pickle juices. In addition to reinforcing titration techniques, the instructional...

Andree Walker thought of everything when he wrote this resource. It includes a detailed list of materials and background information links for the teacher. In addition, it has procedures, a macroinvertebrate identification key, and tally...

How many potatoes tall are you? Unearth this rich resource! A reading of John Coy’s Two Old Potatoes begins a cross-curricular exploration of potatoes. Class members read, write, weigh, measure, and experiment with potatoes. Additional...

Comparing the movement of graphs geometrically when small changes are made to the parent function motivates this collaborative discussion on the transformations of functions to their various forms. Vertical and horizontal shifts due to...

Astronomers practice downloading data from a high-energy satellite and translate the data into colored or shaded pixels. As a hands-on activity, they use pennies to simulate high-energy satellite data and they convert their penny...

Learners explore what fossils are, how they are formed, what different types there are and why they are significant to both our present and past geology history. They participate in a hands on fossil observation of their choice and...

Students explore erosion when there are multiple types of sediments. They view a soil separation demonstration jar before and after agitation to determine how and why the layers settled. In addition, they conduct experiments with a river...

Where does all of the carbon dioxide come from that is supposedly leading to climate change? Earth science pupils test animal, plant, and fossil fuels as sources in this investigation. Using an indicator, BTB, they are able to detect the...

Expectant earth scientists examine the bottom side of a leaf and learn the role of the stomata. They consider the gas exchange that occurs through these structures and relate how the climate is changing to its impact on food crops. This...

Help young scientists connect with nature and learn about trees with a fun life science activity. Heading out into the school yard, children choose a tree to adopt, taking measurements, writing descriptions, and drawing sketches of it in...

Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...
