Math for grades 3-4 (ET-3,4)

Online math course for grades 3-4: 18 lessons split into 4 modules. Logic and detectives, Venn diagrams, combinatorics through games, geometry through origami and kirigami. Children learn to reason, classify, build decision trees, and create 3D figures with their own hands.

Missed lessons can be made up with another group

• Module A. Problem-solver clubRules and strategies: draw, tabulate, check edge cases.
• Logic detective 1Who sat where? Working with a simple table.
• Knights and liarsWho tells the truth, who doesn't (2-3 characters).
• Logic detective 2"And/or/not" conditions, traps in wording.
• Module B. Sorting and rulesClassifying objects, inventing features.
• Venn diagramsRed/round/both + games on intersections.
• Sets and the logic of speechAll / some / none, examples and counter-examples.
• Project: mini-posterHow I classify the world (children build their own system).
• Module C. Enumeration boosterHow to avoid chaotic enumeration — lists, order, no repeats.
• Variant treesIce cream, routes, character outfit (decision tree).
• Combination locks and combinationsVariants of 2-3 steps, constraints.
• Tables and gridsRoutes through cells, simple path counting.
• Combinatorics in a gameTabletop mini-game: collect all variants.
• Module D. Symmetry in origamiFolding, finding axes, making mirror patterns.
• Angles and triangles in origamiWhat you get from folds, why it matches.
• KirigamiCuts and what you get when unfolding: snowflakes, rosettes.
• Nets and volumeCube, house, box + faces, edges, vertices.
• Finale: Big quest mixLogic + sets + combinatorics + origami finale.
