Curated OER
Exploring Equations and Y-Intercept
Students graph linear equations using intercepts, find y-intercept, find x-intercepts and graph linear equations that use horizontal and vertical lines.
Curated OER
What Are The Chances
Students calculate the probability of an event occurring. In this probability instructional activity, students differentiate between independent, dependent or compound events. They find the range of the data.
Curated OER
Point-Slope Form
Ninth graders explore the point-slope form of linear equations and graph lines in the point-slope form. After completing the point-slope equation, they identify the slope of a line through a particular point. Students explain the...
Curated OER
Constructing Tangrams
Seventh graders visualize and identify geometric shapes after applying transformations on a coordinate plane. In this tangrams activity, 7th graders construct a set of tangrams and then answer extension questions related to measurement,...
Curated OER
Relating Division and Subtraction
Third graders relate the process of division to subtracting equal groups. Through guided practice and teacher demonstration, they complete division problems using a subtraction method. Students complete problems independently for...
Curated OER
Scale Factor- Surface Area and Volume
Students calculate the surface area and volume of shapes. In this geometry lesson, students create different scales and calculate the volume and area for each shape. They compare and contrast between the different scales and shapes.
Curated OER
Fraction Equivalence
Fourth graders explore fractions. They compare different fractions using fraction bars. Students find equivalent fractions and they use fraction bars to visualize addition of fractions.
Curated OER
Writing a Number Sentence
Third graders analyze word problems. In this number sentence instructional activity, 3rd graders evaluate word problems. Students create number sentences from word problems.
Curated OER
Congruent Triangles - Is This Enough Information?
Seventh graders examine congruence postulates and apply knowledge to triangles in the world around them.
Curated OER
Number Line Math
Second graders use a number line to practice subtraction. In this subtraction lesson, 2nd graders use a number line to count backwards. Students participate in mad math activities and solve problems.
