The Meaning of Exponents
In this algebra worksheet, students calculate problems dealing with exponents as it relates to money and savings, bacterial growth and paper folding. There are 3 different sections with questions.
Illustrative Mathematics
Lines of Symmetry for Quadrilaterals
Explore how lines of symmetry help define different categories of quadrilaterals. Looking at a square, rectangle, trapezoid, and parallelogram, young mathematicians discover that each shape has its own, unique symmetry. Encourage your...
Curated OER
Multiplying Fractions
Fifth graders explore the multiplication of fractions. Using paper folds, 5th graders observe multiplying by a fraction. They extrapolate multiplication problems from studying a written graphic.
Curated OER
Addition and Subtraction of Fractions
Students demonstrate how to solve addition and subtraction of fractions. In this fractions instructional activity, students use folded paper to shade in fractional parts and identify the sum of the parts shaded.
