Unit 1: Place Value, Number Patterns, & Graphing

During Unit 1 in 2nd grade math, we will begin the year gathering and organizing data in more than one way (tally chart, pictograph, and bar graph.) We will also interpret data from tally charts, pictographs and bar graphs in terms of more, less, and equal. As the unit continues, we will be learning to:
1. Read, write, and model numbers up to 1,000.
2. Identify 10 more and 10 less than a number.
3. Describe numbers as odd and even.
4. Extend, create, and identify a rule for increasing number patterns.
5. Collect, organize, and display data in more than one way.
6. Create and interpret tally charts, bar graphs, and pictographs.
