| Objectives | Students will be able to: (1) identify equal-group situations in stories; (2) solve one-step multiplication problems using known facts. |
|---|---|
| Materials | Story cards (market, farm, transport contexts); counters for proof; working frames. |
| Key vocabulary | equal groups, each, times, in all |
| Engage (starter) | (10 min) The word "EACH" spotlighted: "Patties cost $250 EACH... 5 seedlings in EACH row..." — wherever EACH lives, multiplication is hiding. |
| Develop (main) | (35 min) 1. Story surgery: underline the group size and the number of groups in three read-alouds. 2. Solve six one-step problems using 2/5/10 facts (5 route taxis with 4 passengers each; 10 bags of 6 oranges). 3. The each-hunt: pairs find and flag "each" in every story before touching numbers. 4. Author one equal-groups story per pair for the bank. |
| Plenary (close) | (10 min) Two bank stories solved by neighbours; authors confirm the answers. |
| Assessment | 5 of 6 solved with the fact named; "each" flagged in all; authored story valid. |
| Teacher notes | Underline-before-calculate is the comprehension discipline that survives to CSEC — the answer to "what do I multiply?" always lives in the words, not the numbers. |
| Objectives | Students will be able to: (1) double 2-digit numbers mentally (tens then ones); (2) halve even 2-digit numbers; (3) connect doubling to ×2 and halving to sharing between 2. |
|---|---|
| Materials | Whiteboards; doubling ladders; number cards (even numbers for halving). |
| Key vocabulary | double, halve, twice, half of |
| Engage (starter) | (10 min) The recipe rescue: the cornmeal porridge recipe serves 4, but 8 are coming — EVERY amount must double! Double 26 spoons of cornmeal: double 20 (40), double 6 (12)... 52! |
| Develop (main) | (35 min) 1. The split-double method: tens doubled, ones doubled, recombined (34→68, 47→94 with the recombine-regroup). 2. Halving as the undo: half of 68 back to 34 — split, halve, recombine. 3. Doubling ladders: 3→6→12→24→48 (the ladder climbs FAST — exponential wonder). 4. Recipe workshop: double one 4-line recipe; halve another. |
| Plenary (close) | (10 min) Double-or-half tennis: teacher serves a number and a command; class returns fast. |
| Assessment | Doubles 5 of 6 including one regroup; halves 4 of 5; one recipe converted. |
| Teacher notes | Doubling is ×2 wearing casual clothes, and doubling ladders quietly preview the 4s and 8s tables (double the 2s, double again) — October will harvest this seed. |
| Objectives | Students will be able to: (1) solve two-step problems combining multiplication with +/- (3 items at $50, pay with $200); (2) show working in labelled lines. |
|---|---|
| Materials | Two-step story packs; working frames; play money. |
| Key vocabulary | first, then, total, change |
| Engage (starter) | (10 min) The snack-run drama: 3 juice boxes at $50 each, paid with a $200 bill — "the cashier does TWO calculations before the change appears." Step 1: 3×50=150. Step 2: 200-150=50 change. |
| Develop (main) | (35 min) 1. The two-step anatomy: name step 1 and step 2 BEFORE solving, every time. 2. Guided pair: "4 exercise books at $250; how much from $1,500 remains?" 3. Four problems in pairs with labelled lines (Step 1: ... Step 2: ...). 4. Step-spotting drill: three stories read; class calls only the two steps, no computing. |
| Plenary (close) | (10 min) One solution presented; the class checks that BOTH steps wear labels. |
| Assessment | 3 of 4 solved with both steps labelled; step-spotting correct on 2 of 3. |
| Teacher notes | Naming steps before computing is the exam skill — method marks live in labelled lines. Children who leap to answers unlabelled lose marks they earned mentally. |
| Objectives | Students will be able to: (1) read pictographs where one symbol represents 2, 5 or 10; (2) construct a scaled pictograph including half-symbols. |
|---|---|
| Materials | Scaled pictograph exemplars (fruit sales, bus riders); symbol stamps/stickers; data tables. |
| Key vocabulary | symbol, key, represents, half-symbol |
| Engage (starter) | (10 min) The lazy artist's genius: 40 mango sales to draw... 40 tiny mangoes?! No — ONE mango picture = 5 sales, and the KEY tells the world. Eight pictures do the work of forty. |
| Develop (main) | (35 min) 1. Key-reading drills: a row of 6 symbols at 5-each means 30 (tables on duty!). 2. The half-symbol: half a mango = half of 5... but that's not whole! (Use scale 2 or 10 for clean halves; the messiness DISCUSSED is the learning.) 3. Read one exemplar: most sold, least, how-many-more. 4. Construct: pairs turn a 4-row table (counts to 50) into a scaled pictograph, choosing key 2, 5 or 10 wisely. |
| Plenary (close) | (10 min) Key-choice defence: why did your pair pick 5 and not 2? (Fewer symbols, cleaner page!) |
| Assessment | Key-readings 4 of 5; construction with correct key and one half-symbol; comparison extracted. |
| Teacher notes | Scaled pictographs are multiplication meeting data — a symbol worth 5 makes every read a times-fact. Newspapers and NEPA posters use these constantly; bring one real example if you can. |
| Objectives | Students will be able to: (1) demonstrate the month across strands; (2) complete the month-one checkpoint circuit. |
|---|---|
| Materials | All kits; month sheets; stamps. |
| Key vocabulary | All September vocabulary |
| Engage (starter) | (10 min) Parade: a population card, a zero-monster, a budget sheet, an array, the angle tester. |
| Develop (main) | (35 min) Circuit: S1 read/expand one 5-digit number + one comparison + one rounding; S2 one carry-add and one break-subtract with estimates; S3 one budget problem with working; S4 one array both-statements + tables sample (2/5/10) + one ×10 shift; S5 perimeter of a labelled shape + three angle tests. |
| Plenary (close) | (10 min) Stamps and the October flare: "the 3s and 4s tables, division's return, and FRACTIONS of quantities await!" |
| Assessment | Month sheet across five stations; tables recall and working discipline are the headline records. |
| Teacher notes | Grade 4 September rebuilt arithmetic at scale and lit the multiplication fire — October rides that momentum into the harder tables while it burns. |
