Curated OER
Percent Notation
In this algebra worksheet, students divide circles into equal portions as they explore percents and decimals. They convert between decimals and fractions using ratio and proportion. There are 8 questions.
Curated OER
Similarity and Congruence
Students determine that two figures are similar or congruent by
investigating figures that are similar and figures that are congruent. They prove that two figures are similar or congruent by using definitions,
postulates, and theorems.
Curated OER
Fractions
For this math worksheet, students will read about the definition of fractions. Students will read about and practice equivalent fractions, simplifying fractions and adding and subtracting fractions.
Curated OER
Scale
Students apply concepts of scales to solve problems. In this geometry lesson, students solve real world problems using scales, proportions and ratios. They predict the actual size of a model given the scale drawings.
