Description: This deck guides students through solving percents one step at a time—reducing errors, building confidence, and helping them pinpoint where a mistake occurred. It features six problems where students find the part, given the whole and the percent. Step-by-Step Process: 1️⃣ Identify the part, whole, and percent, marking the unknown with x. 2️⃣ Set up the proportion: part/whole = percent/100. 3️⃣ Cross multiply: part × 100 = whole × percent (Note: While multiplication is commutative, only this order will be recognized as correct by the Boom Card.) 4️⃣ Isolate x by dividing both sides by the same number. 5️⃣ Compute to find x. ✅ First Problem: Color-coded to help students understand how to complete the card. 🪜 Step-by-Step Feedback: At each step, students receive immediate feedback before moving on—allowing them to catch and correct mistakes as they go. ✅ Next Two Problems: Same format as the first, but without color-coding. ✅ Final Three Problems: Students solve the entire card before checking their answer. Perfect for reinforcing procedural understanding, this deck makes percent problem-solving approachable, structured, and engaging for all learners.
