Know what these sort of lines look like and where they are on the axes. y = 3, x = -6, y = x + 3, x + y = 5
e.g. Draw the graph of y = -0.5x - 3
Find the slope of a line using a graph. e.g. Look at a line y = 2x + 1 on a graph. Measure the slope of the line
Find the gradient of a line without a graph by knowing 2 points the line goes through. e.g. A line passes through the points (2 , 5) and (5 , 17). What is the gradient of the line
Know the formula y = mx + c and understand that m = gradient and c = y-intercept. Work out the gradient and y-intercept from the equation of a line without the graph. e.g. What is the gradient and y-intercept of the line y = 4x+2
Know the formula y = mx + b and understand that m = slope and b = y-intercept. Match graphs of straight lines to their equations. e.g. If you have 3 straight line graphs drawn, match them to y = 2x+1, y+x = 4, y = -3x-5
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!
