El castell medieval
The Medieval Castle
With Guisla, students measure land, shop at the market with coins and percentages, and prepare the tower's defense as a team. A complete 25-minute story for grades 5 and 6.
Illustrative imageThe story
Inside the castle, math is the tool the group needs to solve real problems. Guisla, the guide, leads the explorers through the castle grounds, the market and the tower, and every challenge asks the team to share out the work and check the calculations together.
«El castell medieval» is the original Catalan title. The game can be played in Catalan, Spanish and English.
Who Guisla is
Guisla is the game's guide character, in the same warm clay-animation style as the rest of the catalog. She presents each challenge and keeps the story moving.
