Description: Students will practice subtracting two two-digit numbers with regrouping in this fun, scaffolded activity. - Students will see a two-digit by two-digit subtraction problem on each card. - They will need to show all of their work directly on the card as they solve the problem, including entering the new numbers above the minuend as the borrow and regroup (note: students do not HAVE to drag the slashes to cross out the minuend, but it is recommended). - Students will enter the difference one digit at a time as they solve. Scaffolds: - Touch-dots on the subtrahend (smaller of the) numerals in each column - Column (place value) guides - Arrow pointing to the starting column (ones place) - Drag and drop slash mark to show regrouping - Text box to enter new numbers when regrouping Standards: 2.NBT.7 Add and subtract within 1,000… Understand that in adding or subtracting three-digit numbers, …sometimes it is necessary to compose or decompose tens or hundreds. 3.NBT.2 Fluently add and subtract within 1,000 using strategies and algorithms 4.NBT.4 Fluently add and subtract multi-digit whole numbers using a standard algorithm TouchMath™, TouchNumerals™ and TouchPoints™ are trademarks of TouchMath Acquisition, LLC.
