Use subtraction to plan a harvest lunch! This charming title, that has been translated into Spanish, challenges young readers to practice two-digit subtraction and STEM skills to plan food, games, and more. For the first game, subtract 24 apples from 50 apples, leaving 26 apples for other activities! Practical examples like this, along with helpful mathematical diagrams and charts, show children that subtraction cannot only be very useful, but can be easy and fun!
