Show at least two different ways of making the following numbers. a. Use matchstick bundles to make 125. b. Make 145 using a ginladi. c. Make 170 on a number line.
(a)
Answer
125 = 1 bundle of 100 + 2 bundles of 10 + 5 loose sticks. Alternative: 125 = 12 bundles of 10 + 5 loose sticks.
(b)
Answer
145 = Jump 100 + Jump 40 + Jump 5. Alternative: 145 = Jump 50 + Jump 50 + Jump 45.
(c)
Answer
170 = Start at 0, jump 100, then jump 70. Alternative: Start at 150, jump 20 more.
Explanation
(a) Using place value, 125 has 1 hundred, 2 tens, and 5 ones. (b) A ginladi (number line) allows jumps of different sizes to reach the target number. (c) On a number line, 170 can be reached by various jump combinations.
