Math Champions Celebration: Reviewing Numbers, Operations & Sizes! 🌟🏆
Congratulations, phenomenal young mathematicians! You have learned so much in Unit 2: counting up to 20, identifying tens and ones, adding groups with the plus sign (+), taking away with the minus sign (-), and measuring length, weight, and capacity! Today, we review and celebrate all these fantastic superpowers so we are ready for our electronic assessments!
⭐ Number Sense & Operations Review
• Numbers 11 to 20: 10 + ones.
• Adding puts groups together: 10 + 5 = 15.
• Subtracting takes items away: 8 - 3 = 5.
• Comparing: 19 > 14 and 12 < 18.
📐 Measurement Review
• Length: Compare baseline to find taller and shorter.
• Weight: Heavy tilts down; light rises up.
• Capacity: Full has liquid to the brim; empty has none.
