Welcome & Course Approach
Welcome to our math review series! Each post hones in on essential math skills using a clear, step-by-step, hands-on practice system built to boost your confidence and help you truly master the material.
We’ll follow this consistent structure throughout all four posts in the series. Future entries will move into more advanced concepts while continuing to reinforce these core foundations. Pro Tip: Set aside a dedicated notebook for your handwritten work. Regularly review signed number rules and percent conversions—they show up in nearly every upcoming math topic.
Feel free to let me know if you’d like me to tweak the language, include extra examples, add placeholder images for the handwritten solutions/number lines, or develop the next post in the series.
How we will practice:
1. Review the example note-taker (key concepts paired with fully worked examples).
2. Examine real handwritten solutions (authentic student-style work that highlights common methods and typical mistakes).
3. Work through blank versions of the same problems.

intro to descriptive statistics : Unlock the power of descriptive statistics in this clear, beginner‑friendly lesson on data sets and their distributions. We walk step by step through mean, median, and mode, including how to choose the correct median when you have an odd versus an even number of data points. Then we dive into the shape and spread of data using box plots, dot plots, histograms, frequency charts, and the five‑number summary. You’ll learn how to interpret the minimum, Q1, median, Q3, and maximum, and how they connect to box‑and‑whisker plots so you can quickly describe any data set. We also compare bar charts and histograms, plus vertical versus horizontal box‑and‑whisker plots, and explain why a horizontal display can make the shape and distribution of your data easier to see. By the end of this video, you’ll be ready to read and create graphs that tell the real story behind your numbers.
4. Finish the homework assignment.
5. Receive instructor feedback.
6. Assess your understanding with the Google Forms quiz.
This approach blends straightforward explanations, visual and handwritten models, focused deliberate practice, and quick feedback — a combination shown to improve long-term retention.
