🔢 Counting Numbers

Counting is the foundation of mathematics! In Grade 2, we extend our counting skills up to 1000.
• Forward counting in sequences means moving ahead one step at a time (+1) or following a given numerical path.
• Backward counting means stepping down one value at a time (-1) from any 3-digit number.
• Skip counting allows you to count large items quickly by jumping over numbers using fixed intervals (2s, 5s, 10s, or 100s).
• Clustering means arranging scattered items into organized equal groups (like groups of 10 or 100) so they are easier to track.
• Base-ten blocks are physical tools that represent values: a single unit cube is a One, a vertical rod of ten cubes is a Ten, and a flat square grid of one hundred cubes is a Hundred.
