Use positive and negative numbers in context such as temperature and position them on a number line; state inequalities using the symbols < and > (e.g. -3 > -5, -1 < 1) Find the difference between a positive and a negative integer, or two negative integers, in context.
Perform addition and subtraction with negative and positive combinations.
Perform multiplication and division with negative and positive combinations and understand why operations involving 2 negatives will produce a positive solution. Understand the idea of reflection on the number line caused by multiplication or division by -1.
Recall all addition and subtraction facts for each number to 20. Use this to solve problems involving small or large numbers.
Derive and recall all number pairs that total 100. Add or subtract mentally pairs of two-digit whole numbers (e.g. 47 + 58, 91 - 35).
Use the symbols <, > and = correctly.
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!!
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!
