This teaching slides resource introduces repeated halving of lengths, building understanding of how halving again and again produces halves, quarters, and eighths and why the whole length always stays the same size.
Slides begin by revisiting length as a concept and the idea that more parts means smaller parts, before moving into halves and quarters of a length. The "we do" sequence then guides students through halving each part again to form eighths, with students drawing the midline of each part on-screen.
What's included:
Introductory slides revisiting length as how long an object is, height, and distance between two points and how whole length split into smaller parts - the key understanding that more parts means smaller parts
Practice slides to draw the midline of each quarter to form eighths through repeated halving
