Concepts in Algebra
Study Islamic achievement in mathematics by exploring the six standard forms of equations. High schoolers will review the six forms of equations of Al-Khwarizmi. They solve equations using different forms. Links and resources are...
Curated OER
Angles
Learners identify obtuse and acute angles in comparsion to a right angle. They identify obtuse, acute, and right angles. Pupils use "Shape Measure" to construct obtuse, acute, and right angles. They review line segements to locate right...

Comparing Fractions
Young mathematicians compare two fractions with like denominators and then move to the next level to compare fractions with unlike denominators. They will first try to use mental math to make educated guesses. There are a few guidelines...
Curated OER
Systems of Equations and Real Life
What a great classroom resource! The intention of this lesson is to show that real-world math can and should be applied to the community in which your high schoolers reside. The class relates properties of equations to solving for...

Fact Families
With a few extra numbers, these fact families would be complete! After looking at an example, scholars write in the sums and differences for six equations as part of three different fact families. This is really for beginners to this...
Curated OER
Factors of Numbers from 66 to 100
Finding factors requires practice and a logical system, so help scholars develop this skill with these problems. They write out the factor list for 9 two-digit numbers and then circle the factors from a list for four more numbers....
Curated OER
Symmetry
Where is the line of symmetry? Learners begin by drawing in a line to split three images evenly in half, using an example as reference. Encourage them to think about physically folding the picture to solidify this concept. Next, they do...
Curated OER
Multiplying
As scholars become more confident with their multiplication facts, give them some two-digit practice problems to solidify their skills. They solve 30 vertically-aligned problems, regrouping where necessary. All of these have one 2-digit...
Curated OER
Reading and Writing Numbers
Those are some long numbers! Scholars write number-form digits in word form and vice versa. The first eight are six-digit numbers and the next eight are seven-digit numbers. There are two examples to get them started. Remind scholars to...
