IXL's second-grade math module covers more than 200 specific skills in 24 categories, including estimation and rounding, data and graphs, and measurement. Teachers can easily find topics that align to specific Common Core standards or other grade-level appropriate topics. Teachers should know that very few of these activities teach concepts; rather, these drills offer practice and assessment, including helpful reports on kids' progress. Plan on teaching this material separately in class, as the program's explanations for wrong answers are somewhat superficial.
Some kids, however, will enjoy trying out new concepts and may learn best through trial and error. Let these students explore at their own pace. Using the program in this way, be sure to review progress reports to pinpoint areas for improvement, in the form of either in-class supplements or extra drills on the site (or Chrome app). Alternately, you might also use the drills as a quick, fun, and easy way to administer tests or quizzes, or to prepare kids for upcoming standardized tests.Continue reading Show less
Key Standards Supported
Measurement And Data
Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.
Measure the length of an object twice, using length units of different lengths for the two measurements; describe how the two measurements relate to the size of the unit chosen.
Tell and write time from analog and digital clocks to the nearest five minutes, using a.m. and p.m.
Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately. Example: If you have 2 dimes and 3 pennies, how many cents do you have?
Number And Operations In Base Ten
100 can be thought of as a bundle of ten tens — called a “hundred.”
The numbers 100, 200, 300, 400, 500, 600, 700, 800, 900 refer to one, two, three, four, five, six, seven, eight, or nine hundreds (and 0 tens and 0 ones).
Count within 1000; skip-count by 5s, 10s, and 100s.
Read and write numbers to 1000 using base-ten numerals, number names, and expanded form.
Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.
Add up to four two-digit numbers using strategies based on place value and properties of operations.
Operations And Algebraic Thinking
Fluently add and subtract within 20 using mental strategies.2 By end of Grade 2, know from memory all sums of two one-digit numbers.
Use addition and subtraction within 100 to solve one- and two-step word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.1
