# Stage 1 Maths Week 6: Doubling, Halving & Symmetry | EAST FG18/2DS12 | Slides+ Differentiated sheets **Price:** $12.00 AUD **Seller:** TeachBuySell Seller **Year Levels:** year1, year2 **Subjects:** mathematics ## Description (seller-submitted) Teach a full week of Stage 1 maths with this ready-to-go unit, based on the EAST Maths Explicit Teach Plans FG18 (doubling and halving) and 2DS12 (transforming and representing 2D shapes). Students find a half, then half again to make a quarter, and recreate the whole by doubling. They learn that halving and doubling are opposites. Then they fold shapes to find lines of symmetry, create two- and three-shape patterns, and combine and split shapes to make new ones. WHAT'S INCLUDED • 83-slide PowerPoint: every lesson follows I Do → We Do → You Do. It includes warm-ups, learning intentions, success criteria, worked examples, whiteboard checks, games, brain breaks and thumbs up/side/down reflections. Teaching notes are on every slide. • 15 differentiated worksheets (printable PDF): Level 1 Support, Level 2 Benchmark and Level 3 Extension for each day. • 5 answer keys, one for each day, covering all three levels. • A one-page teacher guide: when to use the sheets, choosing a level, page numbers for printing, and daily tips.
