Here is a sample blackboard plan with descriptions of the pictures, based on the image you sent: Blackboard Plan: Subtracting Two-Digit Numbers (with Borrowing) 1. Let's Subtract Vertically! Problem: 74 - 32 Calculation: c 74 \\ -32 \\ 42 \\ 2. How to Subtract 45 - 27 (Using Vertical Form) Problem: c 45 \\ -27 \\ Step 1: Look at the Ones Place Can we take 7 from 5? No. (Picture: Show 4 tens blocks and 5 single blocks.)* Step 2: Borrow from the Tens Place Take 1 ten from the 4 tens. Now we have 3 tens. Add 10 ones to the 5 ones. Now we have 15 ones. (Picture: Show 3 tens blocks and 15 single blocks. An arrow shows one ten block changing into ten single blocks.)* Step 3: Subtract the Ones 15 - 7 = 8 (Picture: Show 3 tens blocks and 15 single blocks, with 7 single blocks crossed out, leaving 8 single blocks.)* Step 4: Subtract the Tens 3 - 2 = 1 (Picture: Show 3 tens blocks, with 2 tens blocks crossed out, leaving 1 ten block.)* Final Calculation: c 034155 \\ -27 \\ 018 \\ The answer is 18. 3.
