Target learners: age_replace (Kenyan context)

Explain what a model is and why we use models to represent real situations.
Identify different types of models: physical (scale), pictorial (diagrams), and mathematical (equations, graphs).
Create simple physical and pictorial models to represent Kenyan everyday situations (e.g., household water use, maize storage, matatu seating, school garden layout).
Translate a simple real-life problem into a mathematical model (using numbers, ratios, charts) and use it to make predictions.
Test and check a model by comparing its predictions with evidence or measurements and suggest improvements.
Communicate model assumptions, steps and conclusions clearly using diagrams, labelled sketches, or simple reports.

Hands-on & group activities

Build a physical model: In groups, construct a scale model of the school garden using cardboard, sticks and paper labels. - Steps: measure garden area, choose scale (e.g., 1m = 1cm), draw plan, place crops. - Learning focus: scale, measurement, spatial planning.
Market-price model: Collect prices of 3 common vegetables from the local market in Ksh. Create a bar chart and use it to predict cost for a larger quantity (use ratio/proportion).
Water-use model: Observe household water containers and estimate daily water use. Represent data with pictorial graphs (drawings or stickers). Discuss ways to reduce waste.
Role-play & flow model: Model how passengers board a matatu during peak times. Use counters or students to simulate flow and suggest improvements (safety, fairness).
Simple mathematical modelling: Given number of maize sacks and weight per sack, predict total weight and how many sacks fit in a lorry. Write an equation and solve.

Classroom demonstrations

Use string and sticks to create a scale map of a neighbourhood; mark key features (shops, schools, waterpoints).
Use maize kernels or pebbles to represent data points in probability or statistics lessons (easy to count and locally available).
Show how a simple linear model can estimate travel time between two towns using average speed (link to local road examples, e.g., Nairobi–Mombasa leg for older learners).

Home & community tasks

Ask learners to model monthly household expenses on a simple table, then draw a pie or bar chart (use Ksh and local categories).
Invite an elder to explain traditional models (e.g., seasonal planting calendars) and compare to learner-created models.

Activity: Modelling water use for a small household

Observe: Record number of water containers and volume (in litres) used for cooking, cleaning and drinking for one day.
Represent: Create a table and a pictorial bar chart (each cup icon = 5 litres).
Predict: If household increases by 1 member, estimate extra water needed per day using proportion.
Test & improve: Compare predicted value with an actual measurement (next day) and update model as needed.

Success criteria: clear table with units, pictorial chart, correct proportional calculation, short written conclusion (2–3 sentences).

Performance task: Groups present a model (physical or mathematical) of a local problem and answer questions on assumptions and limitations.
Short quiz: Define model types; match real-life situations to model choices.
Project mark scheme (simple rubric): clarity of representation (0–4), correctness of calculations (0–4), testing & improvement (0–2), presentation (0–2).

Cardboard, string, sticks, clay, paper, markers.
Local items for counting (maize kernels, stones, beans) for data models.
Measuring tape, kitchen scale, jars (for volumes).
Community sources: market price lists, water bills, local weather station or radio reports for rainfall data.

Support: Provide templates (grid paper, simple table) and concrete counters for learners who need more guidance.
Extension: Older or faster learners create algebraic expressions or use spreadsheets on a phone to model and graph results.
Safety note: When doing field or water measurements, always ensure adult supervision and safe handling of containers and tools.

Teacher tips:

Use local examples—gardens, markets, matatu routes—to make models meaningful.
Emphasise assumptions: every model simplifies reality; discuss what is left out.
Encourage clear labelling (units, scales) so models can be checked and reused.
