Chapter 7, Lina’s Family, uses a family setting to introduce simple addition and subtraction. These questions revisit adding and taking away small numbers.
Practice Questions
Q1. Lina has 4 family members at home, and 3 relatives visit. How many people are there now?
4 + 3 = 7 people.
Q2. If 2 people leave after the visit, how many are left at home?
7 − 2 = 5 people.
Q3. Write an addition sentence for “3 plus 5”.
3 + 5 = 8.
Q4. Write a subtraction sentence for “9 take away 4”.
9 − 4 = 5.
Q5. A family has 5 members. 2 more join, then 1 leaves. How many are there finally?
5 + 2 = 7, then 7 − 1 = 6 members finally.
Why These Help
Word problems about a family connect the abstract idea of adding and taking away numbers to real situations children already understand, like people joining or leaving a gathering.
Frequently Asked Questions
Q. Why do word problems about families help in learning addition and subtraction?
