Course Overview

The source curriculum is presented as a complete recorded video edition of Get Ready for Grade 4 Mathematics. Representative lessons include “Place value blocks”, “Order doesn't matter when purely multiplying” and “Finding missing side length when given perimeter”. These recordings give concrete examples to revisit while building mathematical reasoning, clear notation and worked solutions. Their place in the lesson list is preserved, so you can return to a particular explanation without losing its source position. Introductions, demonstrations, examples, reviews and compilations remain included whenever they appear in the original playlist. Reading a lesson title is useful for locating a topic; working through its reasoning and checking a practice attempt is what makes the recording valuable for learning.

How to study the course

• Videos 1–16: this part of the source list includes “Place value blocks” through “Subtracting: three digit numbers and basic regrouping”. State the quantities and conditions before calculating. Keep a brief working note, revisit an unclear explanation and test one example before moving to another part of the material.
• Videos 17–32: this part of the source list includes “Subtracting: three digit numbers and regrouping” through “Examples relating multiplication to division”. Keep equivalent expressions or representations connected. Keep a brief working note, revisit an unclear explanation and test one example before moving to another part of the material.
• Videos 33–48: this part of the source list includes “Fraction basics” through “Comparing fractions with greater than and less than symbols”. Check each operation with a small example before extending it. Keep a brief working note, revisit an unclear explanation and test one example before moving to another part of the material.
• Videos 49–65: this part of the source list includes “Comparing fractions visually and on number line” through “Finding missing side length when given perimeter”. Explain a result in words as well as symbols. Keep a brief working note, revisit an unclear explanation and test one example before moving to another part of the material.

Who is this for?

This course suits students, returning learners and anyone strengthening the specific mathematics named in the course. It also provides a recorded reference for revisiting a topic after an earlier lesson or study attempt. Choose examples appropriate to your background and allow time to work through the method instead of judging understanding only by how familiar the terminology sounds.

Before you start

Comfort with the preceding arithmetic or algebra skills is useful. Keep paper, a pencil and a calculator when a lesson uses one. Grade-specific courses assume the learner’s earlier grade-level knowledge.

Put the lessons into practice

Build a small worksheet using the kinds of quantities, expressions or situations demonstrated in the recordings. Solve each item, show the intermediate steps and explain why the chosen operation or rule applies. Include one example that is easy to check and another with a changed condition. Use a drawing, number line, table or substitution check when that representation is taught. Compare the result with the original question, then explain one common mistake and how you would notice it.

This optional study activity is provided by WikiFree for independent practice. Keep your working notes and use the relevant classroom recording to check a step, definition or interpretation. It is not an instructor-marked assignment.

Certificate / Assessment

Watching the public videos and using WikiFree completion tracking does not award a certificate, academic credit, an examination voucher or instructor assessment. Use your practice output to review what you can explain and repeat independently. The recorded lessons provide study material; completion tracking records your progress through that material.
