Looking for Pythagorean triples
|
Give the learners the following three tables that show square numbers. Ask, “What is in the same about each set of three shaded numbers?”
After a while the learners should state that “the two lowest numbers in the triple add to the largest number.”
Record the results as equations:
| 62 + 82 =102
| 52 + 122 =132
| 72 + 242 = 252
