Today your child learns to raise fractions to a power. How do you square a fraction? You square the top of the fraction (numerator) and then you also square the bottom of the fraction (denominator). This is really very easy and in a way is additional practice of the concepts learned over the last few […]

# Lesson 130 of Doodles Do Algebra

Yesterday your child learned to raise a polynomial to a power, and today he learns to raise a polynomial to a power. It is essentially the same, only he will need to use the distributive property (what we call hippo hopping) to do the multiplication of the terms. DoodlePoodle explains this very well on the […]

# Lesson 129 of Doodles Do Algebra

Today your child learns to raise a monomial to a given power. The best way to explain to her is to read the definition that DoodleTwo gives on the worksheet out loud to her and then walk her through the example. This is actually a pretty easy concept to learn, just examples tend to be […]

As a bonus, and for practice your child gets to pick one of the two problems and solve it all the way after writing down the equations. Answers: 1. First […]

# Lesson 123 of Doodles Do Algebra

Today your child learns how to expand the solving of 2 unknowns using the various elimination techniques he learned last week. Today we do 3 unknowns and 3 equations. It is essentially the same process as he learned last week. The only difference is that today he has to keep track of which equations he […]

# Lesson 122 – Doodles Do Algebra

Today your child practices solving another one of those “mental math” problems that he worked on at the beginning of the course only this time he can use the techniques for solving two independent equations that have 2 unknowns. DoodlePig helps your child set up the problem, and it is kind of an easy one, […]
