Simple Interest Formula
Interest = principle × rate × time
• I = prt
read as “I am pretty ”
Distance = rate × time
• d = rt
remember as dirt
Speed, Distance and Time
Remember the formula triangle
D = distance traveled
S = Average speed
T = Time taken
You can use the formula triangle in the following way:
If you need to find D, cover up D in the triangle and you get S × T
If you need to find S, cover up S in the triangle and you get
If you need to find T, cover up T in the triangle and you getThe following video shows how to use the average speed pyramid or triangle and the acceleration triangle.
Linear Equations (Slope-Intercept Form)
Begin, Move: the use of m and b in y = mx + b
To graph such a line equation, begin at the value of b, then move according to the value (slope) of m.This is the video form of a mnemonic (memory) device It can help students learn the important aspects of the slope-intercept (y = mx+b) form of linear equations.
