Space isn't in the Key Stage 1 programme of study for England; "Earth and space" is taught in Year 5. These games introduce the big ideas early, for ages 5 to 7, and link to the KS1 topics on seasons, day length and light. Every question is read aloud, including the answer choices.

• Day and Night: the Earth spins, so the side facing the Sun has day. Medium lets children spin the Earth themselves; Hard covers days, years and sunrise.
• Moon Shapes: naming the Moon's phases, then putting them in order from new moon to full moon. The Moon reflects sunlight rather than making its own.
• Our Star, the Sun: which things make their own light, then facts about the Sun and sun safety.
• Space Explorers: rockets, astronauts, satellites and telescopes, then famous firsts like Yuri Gagarin, Neil Armstrong and British astronaut Tim Peake.
• Meet the Planets: recognising each planet from a picture or a clue, then planet facts.
• Planet Line-up: the order of the planets from the Sun, building up to all eight. A rhyme helps: "My Very Easy Method Just Speeds Up Naming".
• Big and Small: things in space are drawn the same size here, so children have to know which is really bigger.
• Star Pictures: join the stars to draw constellations such as the Plough and Orion, then recognise them by shape.

Stars are saved on this device only. There are no wrong-answer penalties: a wrong tap just fades that choice.
