Calculosaures: a dinosaur math game for young explorers

Calculosaures is a dinosaur math game for Android in which mental calculation becomes an expedition. A child picks one of 16 dino companions and explores five territories, one per school year from grade 1 (CP) to grade 5 (CM2).

Nearly 70 skills from the French primary school programme wait in the nests of the jungle. Natural history and early science often start with dinosaurs, which makes this a friendly bridge to our own topics.

Starting the expedition

1. Install Calculosaures from Google Play.
2. Choose a dino among 16 companions and meet Rexou, the mascot.
3. Open the territory of your school year.
4. Visit a nest, which is a skill, and solve ten calculations.
5. Win up to three footprints, then read the tip after any mistake.

What you will find inside the dinosaur math game

• Five territories: the Flowering Plain for grade 1, the Giant Forest for grade 2, the Vine Marsh for grade 3, the Pterosaur Cliffs for grade 4 and the Rumbling Volcano for grade 5.
• Nearly 70 skills: complements to 10, doubles, halves, all tables, giving change, multiplying by 10 or 100, first fractions, tenths, hundredths and decimals.
• An adjustable timer that can also be switched off.
• A daily mission of 12 mixed calculations with doubled experience points.
• Coconut rain, a duel on one screen and visual aids such as dots, fingers and coins.
• More than 40 egg badges that start as fossils, plus 12 ranks, and no advertising.

Who it is for

Primary school children enjoy the story, and parents like the Progress screen showing playing time, success by type of calculation and notions to review.

The duel mode lets a parent and child, or two siblings, play at their own level on the same screen. Progress stays on the Google account.

A first step toward scientific thinking

Curious children who like fossils and eggs are already asking science questions. Counting skills built here prepare them for the measurement and data work found in our physics and chemistry courses when they reach middle school.

Older siblings can use the AP Physics 1 worksheets while younger ones explore the jungle, which gives the family a shared evening routine.

Eggs, fossils and ranks

More than 40 badges look like eggs in amber, jade, gold or legendary versions. Until earned they appear as fossils, and once a goal is reached they hatch on the screen.

Along the way a child climbs 12 ranks, from Brand New Egg to King of the Dinos. This gives young players a clear picture of how far they have come.

The Progress page adds a more serious view for parents: playing time, success by type of calculation, strengths and notions to review. Together the two views balance fun and information.

Tips for parents

• Turn the timer off for a child who feels anxious, then switch it on gradually.
• Use the daily mission to start a regular, brief habit.
• Ask your child to explain a tip in their own words.
• Review the Progress screen together every weekend.
