Once Upon Coding

Here's a set of 20 #dinosaurs self-correcting task cards to do some #mental #calculation and get started with equation solving. Just fold the card to have the solution on the back. Level 1 uses only additions and subtractions. You will find two versions in the file: one "ink saving" (= no background), the first 10 pages, and the second in full color (the next 10 pages). So be careful when printing. If, despite all my vigilance, you observe an error, do not hesitate to inform me immediately by me
