Essential Questions for Georgia Grade 2 Math Standards
- Students must continue to develop an understanding of numbers and how to represent them. First, students should be comfortable using multiple representations of numbers to connect symbols to quantities. Example questions could include how to represent 5,125 as individual units (5,000 + 100 + 20 + 5) and how to represent $3.25, using a picture of money, on paper.
Second, students should build fluency with multidigit addition and subtraction. An example question could involve how to add and subtract two whole numbers up to three digits, such as 100 + 90 or 220 - 120. Third, students should understand simple multiplication as being repeated addition. An example question could involve how to represent five times five as being five added to itself five times.
Next, students should be able to compare fractions. An example question could involve comparing two pictures of a half-full cup and adding them together. Lastly, students should be able to interpret quantities and relationships using the mathematical expressions =, >, < and ≠. An example question could involve using a blank space between numbers and having the student fill in the appropriate expression. - Students must understand length, time and temperature. Students should be familiar with inches, feet, yards, centimeters and meters as units of measurement. An example question could include using a measuring stick to measure various object in inches, feet and centimeters and recognize which type of measurement is most appropriate. Also, students should be able to tell time to the nearest five minutes and understanding relationships of time. Example questions could include asking how many seconds are in a minute or using a picture of a clock and asking the time to the nearest five minutes. Lastly, students should be able to read a thermometer and determine reasonable temperatures in a given context. An example question could involve showing a picture of a snowy and/or sunny place and asking for the most likely temperature.
- Students must understand basic and compound geometric shapes. Students should be able to describe plane figures such as triangles, squares and rectangles. An example question could involve asking students to draw different shapes and how to describe them. Students should also be comfortable classifying solid geometric figures. An example question could involve showing pictures of polygons and asking what they are based on the number of sides they have.
- Students must pose questions and collect and interpret data about themselves or their surroundings. This includes creating simple tables and graphs and interpreting picture graphs, such as Venn diagrams. An example question for creating graphs could involve asking students to make a bar graph based on the number of different contents in a small bag of trail mix. An example question for interpreting graphs could involve showing a simple Venn diagram and asking students to talk about its meaning.
