Description: Students will practice three-digit subtraction with regrouping (borrowing) in this scaffolded activity. Students will see a three-digit minus three-digit math sentence in the standard algorithm (vertical) form. They will fill in each box one at a time to form a three-digit or two-digit difference. Students will SHOW ALL OF THEIR WORK DIRECTLY ON THE SLIDE (including the regrouping/ borrowing)!!! If a student makes a mistake, they will receive immediate feedback of where the mistake(s) are, so they can make corrections and resubmit. Scaffolds: - Touch-dot numbers on the subtrahend (smaller of the numerals) in each column - Column (place value) guides - Arrow pointing to the starting column (ones place) - Number line to assist in counting backwards This mini deck is perfect for IEP specially designed instruction or small group tutoring sessions. 2.NBT.7 Add and subtract within 1000, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method. 3.NBT.2 Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction. 4.NBT.4 Fluently add and subtract multi-digit whole numbers using the standard algorithm.
