Answer a question with the data

one step, then two

G3–4

reading the graph is the first step, never the whole questionFish7Hamster6Turtle4Rabbit6How many more chose Fish than Turtle?7 − 4 = 3now one that takes two stepsFish and Hamster together,how many more than Turtle?7 + 6 = 1313 − 4 = 9step 2 uses step 1’s answer, not a new countfind the numbers the question needs, then do the arithmetic on them

How this one works

How

pull out only the numbers the question needs, then do the math on them.

Best when

the question asks how many more, how many altogether, or how many are left.

seen one of these on a test? See it on a real question: TEKS 3.8A, reading a table, graph or plot, or TEKS 4.9A, dot plots and stem-and-leaf plots.
