Second grade math is where mental strategies become second nature. This set of 2nd grade math lessons covers the Common Core ground for the year: fluent addition and subtraction within 20 (2.OA), three-digit place value with hundreds, tens, and ones (2.NBT), measuring length with appropriate tools (2.MD), recognizing and drawing shapes by their attributes (2.G), and telling time and counting money (2.MD).
The decks follow a consistent teaching rhythm — model, practice together, check understanding — with visuals that make the math concrete: base-ten representations for place value, number lines for mental strategies, and clock faces students can read along with you.
Use them as-is or open a deck in Chalkie to adjust: bump the numbers up or down, add a word-problem slide with your students' names, or split a long deck across two days. Lessons are free to view, and a free account unlocks full editing. It is an easy way to claw back planning time each week.
