We’ve just completed our first unit of study that revolves around integers(…-3, -2, -1, 0, 1, 2, 3,…), computation with integers, variables, variable expressions and graphing in a coordinate plane. The students took their first major assessment on Friday the 24th and results will be posted as their grades are completed. Please check PowerSchool for an update.
The upcoming week we will begin to work in chapter 2 with properties of numbers. There will be more vocabulary than normal in this chapter – the words/phrases for the first week will include:
Simplifying a variable expression
Combining like terms
Solution to an equation
The lessons will revolve around the vocabulary above. Students should be able describe what each of the above phrases mean and should also be able to give an example (using their notes if needed) of each one. These words and phrases come from sections 2-1, 2-2, 2-3 and 2-4 in their textbook. Videos to support these lessons can be found at the Pre-Algebra website under resources/videos/PA Chapter 2.
Finally any student not achieving at least 21 out of 23 on a ‘calculator assessment’ will not yet have access to the use of calculators in the classroom. If your child has not yet earned that grade, they should expect to spend some time in remediation to improve their skills and re-quiz throughout the week.
Week 5 of our course is going to be a week heavy with media. We’ll start the week with a lesson on solving equations with variables on both sides of an equation. Tuesday should provide us time to work with special formulas and equations – for example we will take the formula to convert °C to °F and manipulate it to create the °F to °C formula.
On Wednesday we will complete a mid chapter assessment on the first 5 sections of chapter 2 and will then watch a diving video to introduce ratios and rates. Thursday will be an additional video relating to ratios followed by the beginning of a lesson on solving proportions. We’ll end the week with a film clip from the movie The Bone Collector where a detective uses proportions to accurately determine the shoe size of a suspect.
