# UnLock Geometry

## Classifying Triangles by Side Length

Warm Up
Each day your child will begin with a short 5 question Warm Up covering material from the day before. This does two things. First, it's a quick check to let us know that they remember what they learned. Second, it helps their brain to switch gears into "math mode" getting them ready to learn.

Learn
Then it's time for the engaging video lesson taught by Alesia Blackwood, utilizing her unique style of breaking math concepts into bite-size chunks that are easier to understand & apply!

Practice
Next, we'll take them through 10 Practice Problem questions covering JUST what they learned in the video. After each question, they view a complete solution so that they can compare their work to ours in case they missed a step, etc. If, after going through all 10 questions, they are ready to move ahead, GREAT. If not, they may open a NEW set of Practice Problems and we'll record their best effort for their grade. They can do this as many times as needed, we'll give them NEW questions each time!

Review
After Practice Problems, they move on to 10 Stay Sharp questions that cover material from previous lessons to make sure concepts are kept fresh and continuously reinforced so that it makes it into long-term memory.

Challenge
We include a Challenge Yourself question that is a student favourite! It's a chance to earn "extra credit" and stretch their math skills for bonus points.

Reference
Each lesson also comes with Reference Notes that may be printed or viewed online.

Quiz, Review, and Test
Every two or three days students complete a 5 question Quiz after the daily lesson, making sure they don't need to review a concept before moving on. The unit concludes with a Unit Review and a Unit Test and we also give you a Mid-term and a Final Review and Test.

You have access to Grades and more from your convenient Parent Dashboard. You may view each attempted assignment when it was completed, how long was spent on it, and each score. You'll also receive a weekly email of your child's progress.
