Recognize that angles at a point on a straight line total 180 degrees.
Know that angles are measured in degrees and that one whole turn is 360 degrees. Calculate angles at a point.
Decide which of two numbers from 1 to 100 is the larger. From a list of integers up to 100, arrange in ascending or descending order.
Use angles at a right angle and use perpendicular lines. Spot right angles of any orientation on a square grid. Understand the term complementary angles. Also use the rule that angles on a straight line at a specific point sum to 180. Solve problems involving straight line angles. Understand the term supplementary angles. Also use the rule that angles at a point sum to 360. Known as a full turn.
Recognize and calculate with vertically opposite angles. The term 'opposite' will be acceptable.
Understand that when parallel lines are crossed by another line, (interior) alternate angles are created. Solve problems involving the alternate angles including understanding the properties of allied angles, although this term is not examined. The term 'Z' angle is not a sufficient reason for two angles being equal.
We’re loved by both teachers and students globally. Here’s the proof!
Mangahigh turns our students into “math addicts“ who compete with each other for top scores and gold medals. And since the quizzes reward both accurate recall of knowledge and deep conceptual understanding, every hour they spent having fun makes them better mathematicians. Five stars.

I have used Mangahigh in my classroom for over 5 years. What keeps me coming back are the math games and wide range of concepts that are offered. But the best part is the fact that the kids LOVE to play it. I have students beg me to assign them Teacher Challenges! Begging for more math work? I am ok with that!!
Green Elementary School, Allen, Texas
Kids loved it; an ADHD student who has NEVER before been able to focus in the last periods of the day; he wouldn't stop till he got a medal! Absolutely phenomenal! His mother is overjoyed, and the rest of the math staff room were gobsmacked!
