​Find the Mistake

Check if the following answers are correct. If wrong, correct them.

​Find the Mistake

a) 25 + 36 = 511
b) 37 + 58 = 131
c) 35 - 17 = 22
d) 57 - 78 = 21
e) 30 - 17 = 27

Answers: 

a) 25 + 36 = 511 (Wrong)
Correct answer:
25 + 36 = 61
61

b) 37 + 58 = 131 (Wrong)

Correct answer:
37 + 58 = 95
95

c) 35 - 17 = 22 (Wrong)

Correct answer:
35 - 17 = 18
18

d) 57 - 78 = 21 (Wrong)

Correct answer: Not Possible
57 is smaller than 78. We cannot subtract.

e) 30 - 17 = 27 (Wrong)

Correct answer:
30 - 17 = 13

FAQs on Worksheet Solutions: Decoration for Festival - 1

1. How do I count and add decorations for the festival using simple numbers?
Ans. Festival decoration problems teach Class 2 students to count objects, add small groups, and find totals using basic arithmetic. Students learn to combine quantities of flowers, lights, and garlands by counting forwards or using their fingers, then writing number sentences to show the addition. Practice with visual aids helps strengthen number recognition and addition skills needed for everyday situations.
2. What's the difference between using ones and tens when decorating with lots of items?
Ans. Understanding place value with ones and tens helps students organize large quantities of decorations into groups of 10. When counting 23 flowers, students recognise 2 tens and 3 ones rather than counting individually. This grouping method makes addition and subtraction faster and builds foundational skills for working with larger numbers in future mathematics.
3. How do I solve word problems about festival decorations with missing numbers?
Ans. Word problems involving missing numbers in decoration scenarios teach students to identify what they know and what they need to find. If 15 balloons are needed and 8 are already hung, students determine 7 more are required. Reading carefully, drawing simple pictures, and using number sentences helps solve these practical problems systematically.
4. Why do some decoration problems ask me to compare groups of items?
Ans. Comparing groups during decoration activities introduces concepts of "more than," "less than," and "equal to" using concrete examples. When one corner has 12 lights and another has 9, students learn to identify which is greater. These comparisons strengthen understanding of number relationships essential for measurement, ordering, and logical thinking skills.
5. Can I use skip counting to arrange decorations in patterns?
Ans. Skip counting by 2s, 5s, or 10s helps arrange festival decorations into equal rows or repeating patterns efficiently. Hanging lights in groups of 5 or arranging flowers in pairs becomes quicker when students skip count instead of counting one by one. This technique builds mental maths speed and prepares students for multiplication concepts in higher classes.
