Skew Distribution
Slide the class into a skewed view. Learners alter the location of the median relative to the mean of a normal curve to create a skew distribution. They compare the curve to a histogram distribution with the same skewness.
Shodor Education Foundation
Normal Distribution
Does the size of the bin matter? The resource allows pupils to explore the relationship between the normal curve and histograms. Learners view histograms compared to a normal curve with a set standard deviation. Using the interactive,...

Factoring Trinomials
Students factor trinomials using specific factoring methods. In this algebra instructional activity, students factor equations using the difference of squares and foiling. They play a game to enhance their understanding of factoring.
Curated OER
Telling Time By the Hour
First graders explore how to tell time by the hour. They draw the minute and hour hands on a clock to match the time shown by the teacher on the overhead clock. Students write the time shown on a worksheet. They read "The Grouchy Ladybug."

Comparing and Ordering Integers
Learners compare and order integers on an umber line. In this algebra lesson, students differentiate between positive and negative numbers. They plot point in the correct order on a number line.
Curated OER
Polynomials
Learners add and subtract polynomials. For this polynomials assessment, students calculate ten questions using addition and subtraction. Learners use Lego manipulatives to create their own worksheet on polynomials.
