Lesson 135 – Doodles Do Algebra

Today your child extends the concepts of square roots to unknowns. The only point you really need to make sure your child understands is that 2 times 2 is the same as negative 2 times negative 2, the answer is 4. So that means that the square root of 4 could be a positive or […]

Lesson 134 – Doodles Do Algebra

Today your child learns how to take the square root of a fraction. Basically the square root of a fraction is the same as the square root of the numerator divided by the square root of the denominator. The problems for your child to work are simple and build to the idea of taking the […]

Lesson 133 – Doodles Do Algebra

Today’s lesson focuses on teaching your child to extract the square root of any quantity without a calculator or computer. As DoodlePig explains on the worksheet, you simply use a bit of algebra.
