How it's taught
Model stacking during play; provide blocks of appropriate size; celebrate stacking attempts even if unsuccessful; play stacking games (build up, knock down); gradually introduce more complex building challenges
Materials: Large wooden blocks, soft blocks, stacking cups, cardboard boxes
What mastery looks like
Does not attempt to stack; may knock down stacks or scatter blocks
- Picks up blocks but doesn't attempt stacking
- Knocks down adult-built stacks
- Throws or scatters blocks
Beginning to attempt stacking but not yet successful
- Brings blocks together but can't balance them
- Places block near another but not on top
- May successfully stack with adult hand-over-hand help
Successfully stacks two small objects
- Stacks at least two small objects, like blocks
- Achieves stable two-block tower
- May attempt three blocks with some success
- Shows satisfaction when stack is successful
Consistently stacks multiple objects; beginning to create more complex structures
- Reliably stacks 3-4 blocks
- Attempts to build taller towers
- Can restack after tower falls
- Beginning to align blocks carefully
Sophisticated stacking and building; creates intentional structures
- Stacks 6+ blocks
- Creates intentional structures (towers, walls, bridges)
- Carefully aligns blocks for stability
- Experiments with different stacking patterns

Cause and Effect Discovery
Parent helps baby discover that actions produce results — kicking a mobile, shaking a rattle, batting a dangling toy. The agent coaches the parent to observe whether baby connects their own movements to outcomes, building the foundational academic skill of causal reasoning.
Little Scientist
Parent observes baby's systematic exploration of objects — turning, mouthing, banging, dropping, comparing. The agent coaches the parent to recognise these behaviours as scientific inquiry: experimentation, observation, and hypothesis-testing in miniature.
First Marks
Parent offers crayons or finger paint and the agent coaches the parent to observe toddler's first mark-making — scribbles, dots, lines — as expressions of early aesthetic creativity and motor control.
Where Did It Go? — The Dropping Game
Parent drops a toy in front of baby to see if they look down at the ground to find it. Agent guides parent through a natural play sequence that observes early object tracking and the beginnings of object permanence, while keeping baby engaged and happy.
Rules of Play — Learning How Things Work
Parent and toddler play a structured game where the agent guides observation of the child's understanding of basic rules and norms — like taking turns, following simple instructions, and understanding 'gentle' versus 'rough.' Uses everyday play situations to assess social cognition.
Feelings Faces
Parent names emotions using facial expressions, pictures, or a mirror. The agent coaches the parent to observe the toddler's ability to recognise, name, and connect emotions to experiences — building early emotional literacy and contemplative self-awareness.
