January (Grades 6-8)
New Year’s
As a New Year’s resolution, Anton decided to raise his school grades by spending an additional 20 minutes each night on his homework. Prior to his New Year’s resolution, Anton spent an average of 12 minutes a night on his homework, resulting in an average math score of 68%. Keeping his New Year’s resolution, Anton raised his math score to 78%. In February, Anton spent an additional 10 minutes a night on homework, on average, and raised his math score to 83%.
Create a table or graph to chart how much time Anton spent on math homework and his average math score each month.
Use the chart to determine the relationship between the amount of time Anton spends on math homework and his math score.
Martin Luther King, Jr
Martin Luther King, Jr. (MLK) believed that all people were created equal and he helped to make sure that African Americans were treated the same as all other people in America. We celebrate his life on his birthday in January every year, as he is a person who changed the world.
In 1934, MLK attended a private elementary school called Oglethorpe Elementary School. It cost his parents $25 for the year. Today, the average cost of private elementary school is about $11,000 per year.
How much has tuition increased since 1934? What is the average yearly increase from 1934 to 2018?
*CHALLENGE: describe the change in terms of percent increase.

Looking at data gathered to analyze the impact of global warming from the National Snow and Ice Data Center we have the following graph:
Find the rate of change of square miles of ice coverage in December across the years in the graph.
If this trend continues, what will the area of ice coverage be in December of 2018?
