MATH – Data Management/some Number Sense

Spaced out x-axis shows a gradual change:

Compact x-axis shows a more sudden change:

 

We have been interpreting graphs….by noticing what they show (evidence)….and drawing inferences and conclusions

 

We have been comparing different graph types (previously learned in other grades: circle graph, pictogram, bar graph) and how they accurately show data….or how they show estimates. Correct answers to last Friday’s work is shown below….tonight students will be working on bumping up their answer by explaining all of their thinking (how they used benchmarks, etc.)
