About This Skill
How do you write a story about taking away? Kindergarteners practice turning visual scenes into math equations by matching pictures of 'taking away' to the correct subtraction sentences. As questions adapt to their progress, children observe playful examples, like crossing out apples, to find the equation that fits. With voice-guided instructions and instant feedback, this interactive practice helps students confidently use the minus sign and equal sign to show what happens when items are removed.
