Type Study Two paper strips that have a sum of 4 cm can be placed side by side to
measure 4 cm. The two strips are 1 cm and 3 cm.
1+3=4 cm
1 cm 3 cm
Two paper strips that have a difference of 4 cm can be laid on top of each
other to measure 4 cm. The two strips with that difference are 5 cm and 1 cm.
1 cm 5 cm
5-1=4 cm
Problem solving
1 The two measurements that can be measured using one block are 2 cm and 4 cm.
When two blocks are arranged in the following way, 4+2=6 cm can be measured.
4+2=6 cm
When two blocks are arranged in the following way, 4+4=8 cm can be measured.
4+4=8 cm
The length that cannot be measured is 3 cm.
2 If the 3 cm bar is closed to overlap the 5 cm bar, 2 cm can be measured.
3 cm 5 cm
5-3=2 cm
Type Study The weight of a marble is 2, and the weight of one unit weight is 1. The scale
can be balanced by placing 2 unit weights on the left plate.
