What is an integer? How do integers compare with whole numbers? Where do integers show up in real-life situations? Give as many examples as you can think of – we’ll want a big list.
For each of the numbers below, use at least two of your real-life situations to write a sentence which uses that number in a sensible context. Then, draw a picture which could represent your number.
(a)
(b)
(c)
(d)
Are numbers like integers? Could we still use any of our models for a number like this? Explain your thinking.
Draw a number line which includes all of the numbers in the previous two questions. How did you decide where to locate the negative numbers?
For each of the addition problems below, use at least two of your real-life situations to write a story problem which would be answered by that expression. (Be sure to include a question!) Then, draw a picture explaining what a child learning this concept might do to solve the problem.
(a)
(b)
(c)
(d)
Look back again at each of the addition problems you did in the previous problem. Does the sign of the answer make sense from your story? Could you model the addition problem using a number line?
