Solving exercises on pages 22 and 23 of Math 3 Workbook Volume 2, from the Kite series:
Middle Point. Midpoint of the line segment
1. Solve Exercise 1 Page 22 Math Grade 3 Workbook
Problem: Observe the following shapes and name the midpoint between two different points:
Solution Guide: Observe the drawings to find the midpoint between two different points.
Answers:
Point I is the midpoint between points G and H.
Point O is the midpoint between points C and D.
Point O is the midpoint between points A and B.
2. Solve Exercise 2 Page 23 Math Grade 3 Workbook
Problem: Name the midpoint of each line segment in the figure below:
Solution Guide: Observe the drawing and identify the midpoint of each line segment.
Answers:
Point O is the midpoint of line segment PQ (because O is the point between points P and Q; PO = OQ).
Point M is the midpoint of line segment DB (because M is the point between points D and B; MD = MB)
Point M is the midpoint of line segment AC (because M lies between points A and C; MA = MC)
3. Solve Exercise 3 Page 23 Math Grade 3 Workbook
Problem: Observe the number line, choose the correct statement.
a) The midpoint of line segment AB corresponds to the number 4,200.
b) The midpoint of line segment BC corresponds to the number 4,700.
c) The midpoint of line segment AD corresponds to the number 4,500.
Solution Guide:
- Consecutive marks on the number line differ by 100 units.
- Observe the number line to determine the midpoint of each line segment and then answer the questions.
Answers:
We have the following number line:
Upon observing the number line, we see:
a) The midpoint of line segment AB corresponds to the number 4,200.
b) The midpoint of line segment BC corresponds to the number 4,600.
c) The midpoint of line segment AD corresponds to the number 4,400.
So, option a is correct.
4. Solve Exercise 4 Page 23 Math Grade 3 Workbook
Task: Determine which images are related to the midpoint of a line segment.
Challenge: There is a straight steel wire. How to find its midpoint?
Solution: Observe the images and identify the midpoint of the line segment.
Answer:
Images relevant to the midpoint of a line segment:
Fold the steel wire so that both ends overlap. The folding point is the midpoint of the steel wire.
