A standard post-box letter slot is rectangular in shape. Which of these envelopes will fit through the slot without being bent, folded, or rotated?
✅ Answer: C
A rectangular letter slot matches the flat 2D shape of a wide, flat rectangular envelope, allowing it to slide through easily. Other shapes with wrong dimensions or properties will not match the opening. Students confuse shape suitability with size or orientation.
What is the result when you subtract 25 from 80?
✅ Answer: B
Result = 80 - 25. To subtract, regroup 80 as 7 tens and 10 ones. Then, 10 - 5 = 5 (ones place). And 7 - 2 = 5 (tens place). So, 80 - 25 = 55. Option C incorrectly subtracts the tens as 8-2=6 directly without regrouping for the ones. Option D incorrectly adds. Option A miscalculates after regrouping.
Priya had a book with 478 pages. She read 235 pages. How many pages are still left to read?
✅ Answer: D
Pages left = 478 (total pages) - 235 (pages read) = 243 pages. Option A has an error in subtracting the tens place (7-3=3 instead of 4). Option C incorrectly adds the numbers instead of subtracting. Option B has errors in both tens and hundreds place subtraction.
