Your forces list and the course, side by side

Olivia's 40-step forces sequence, checked line by line against the built Grade 3–5 course on 23 October 2026. Each match below names the lesson that teaches it, confirmed from the course build itself. Prepared for Olivia; copied to David and James.
The short version

Your 40 steps, mapped to the course's lessons

Your steps on the left, the course's 53 forces lessons on the right, in the order the course teaches them (Grade 3 → Grade 4 → Grade 5). A green line means the lesson teaches your step in full; amber means in part. Grey steps are your vocabulary videos — no line, because the course teaches those words inside the lessons.

Your list, step by step

The course's forces lessons, and where each appears in your list

One row per lesson, in teaching order. Green = on your list. Red = not on your list — mostly the push-and-pull effects block (the Grade 3 state test asks about it), the investigations, and Grade 5's content.

Which list is more finely split?

On the ground you both cover, nearly one step to one lesson. The totals differ because the scopes differ.

AreaYour stepsCourse lessonsWho goes finer
Gravity26The course — the pull can be beaten, the direction, naming gravity
Magnets49The course — poles, distance, the steel rule, the model
Naming "force" and the kinds of force45Even
Arrows33Even — you add "which force is this arrow showing"
Touching and not touching23Even
Friction95You — you add the why and the slippery drill
Several forces, balanced and unbalanced48The course — your list stops just before this block

Four things from your list the course should take

  1. CAN touch against HAS to touch (your step 18). A magnet can touch; it does not have to. That contrast pair belongs in the touching lesson's examples.
  2. The "slippery means LESS friction" drill (your step 27). The backwards wording is a real trap. The course tests which surface slides farther; it never drills the backwards sentence. A short practice run in Grade 4 closes it.
  3. "Which force is this arrow showing?" (your step 13). The course draws arrows, and it names forces — it never asks the two together. One new question type closes it.
  4. A decision on vocabulary. Your standalone vocab videos, or the course's word-inside-the-lesson. Either works. The courses should do one thing, and that call is James's.

Two wordings to look at

  1. "Applied force" (your steps 7, 37, 38). The course deliberately says "a contact force" instead, and here is the reasoning. Every force is applied — one object applies it to another. Gravity is applied by the Earth. The magnetic force is applied by the magnet. So the name "applied force" does not pick anything out. "Contact force" does: it says this force only happens while the two objects touch. James ruled this on 8 October, so the student word across the courses is "a contact force". Your steps 37–38 also use "applied force" for the table's push on the book — that one is a different force again (middle school names it the support force). The fact itself is already taught: Grade 3 Topic 9, lesson 2 — "Earth pulls the book down. So why doesn't the book fall? Because the table pushes the book up." — and Grade 5 says it again. Keep your chair example; it just doesn't need the label.
  2. "Friction always points opposite to motion" (your step 33) breaks on your own examples. Grip on the monkey bars is friction stopping a slide that never happens. When you walk, friction on your shoe points forwards. The safe wording is already in the Grade 4 lesson: "friction always acts against the direction you are trying to push."
  3. Small one: your step 5 drops the word "some" ("magnets can pull metal objects"). Your step 3 has it right — only some metals. Grade 4 pins it: a magnet always pulls steel.
  4. The vocabulary videos grow with the examples you pick. "Asphalt" needs a video only because step 31's example is asphalt. Sandpaper or a brick needs no video. Picking examples from words the children already own removes most of the vocabulary load.

Changes your list asks of the course — for James

Your edits to the gravity lessons — drop "without touching" from step 1, and drop "the Earth is always pulling" — would change two existing lessons that are there on purpose. That is James's call, and it is now on his list. Also his: when to name "friction" (Grade 3 currently says "the drag back"), and one line of guidance on "a contact force" doing two jobs — it names the touching kind of force, and it is also the test answer for a person's push.
