Sums of consecutive integers
It’s been great watching Simon turn a word problem into an equation today. He was busy with “Sums of consecutive integers” (Practice finding the nth number in a sequence of … Continue reading Sums of consecutive integers
Algebra Visualization
Equations have definitely become our friends now. Simon got really creative during his math lesson and came up with an “Algebra Visualization Kit” – creating an abstract representation of an … Continue reading Algebra Visualization
The Supershape Formula
Thursday night Simon told me he really needed to draw “something about a circle”. We were having an evening walk at the local park so I gave him a stick … Continue reading The Supershape Formula
Equations Continued. A Victory.
Yesterday was a break-through day! Simon finally cracked those equations with variables on both sides, even the ones including parentheses! And this is what helped: just like with programming, he … Continue reading Equations Continued. A Victory.
Equations with variables on both sides
Equations with variables on both sides remain a difficult subject to grasp. Well, all right, we only tried it twice so far. On Monday evening I saw Simon sit down … Continue reading Equations with variables on both sides
Solving basic equations & inequalities (one variable, linear) with Khan Academy
Simon is back on Kan Academy! For the math lessons we decided to dive right into the equations. They are featured in much more detail here than on Brilliant.org (which … Continue reading Solving basic equations & inequalities (one variable, linear) with Khan Academy
Solving Equations continued
From Yesterday’s math class. Simon continued with the equations and managed to complete four quizzes on Brilliant.org within one hour. He neglects writing things down though, trying to solve everything … Continue reading Solving Equations continued
Algebra>Solving Equations>Balancing Scales
This morning Simon was crying bitterly when he thought that the equation to calculate the resistance in a video wasn’t correct. We wrote the solution down together in detail and … Continue reading Algebra>Solving Equations>Balancing Scales
Absolutely beautiful
Look Mom, Simon said today, in math there is something called the absolute value. What is the absolute value of -4,7? It’s 4,7! (I think he learned it from his … Continue reading Absolutely beautiful
Kirchoff’s Current Law
On Monday Simon’s math tutor and I agreed that Simon should try some problem solving involving both math and electricity, considering his current interest. We chose Electricity and Magnetism > Current … Continue reading Kirchoff’s Current Law
Checking Cases
From Friday’s math class (Reasoning Skills > Checking Cases on Brilliant.org):
