# 2nd Grade Mathematics Skills Prior Standards Implementation

### Please go to Current 2nd Grade Math Standards for current resources.

• Number & Operations - Links to previous number and operations standards (e.g. count forward and backward by 1 from any number less than 999; read and write numerals to 999; determine the value of a collection of coins up to \$1.00).
• Algebra - Links to previous algebra standards (e.g. sort objects by 2 or more attributes; identify the unit of a 3-part repeating pattern; show that subtraction is not commutative).
• Geometry - Links to previous geometry standards (e.g. identify, build, draw and compare two and three dimensional figures; identify shapes that have line symmetry; identify position of a whole number on a number line).
• Measurement - Links to previous measurement standards (e.g. understand concepts of perimeter and area; explain what can be measured about objects in the environment; estimate lengths and time intervals).
• Data Analysis & Probability - Links to previous data analysis and probability standards (e.g. pose questions and gather data to answer questions; construct pictographs and bar graphs; explain whether event is likely or unlikely).

### Great Tools: Worksheet Generator - This site will allow you to create printable math worksheets from your browser. Including: addition, subtraction, multiplication, division, mixed problems, fractions, measurement, graphing, telling time, and other charts. Math Teachers' Toolkit - Compilation of resources to help students understand concepts.
