Conquering Sums & Differences to 20 on Mount Kibo
Let's be honest: when our kids hit Sunny Meadow on Mount Kilimanjaro, the challenge kicks in for both of them—and sometimes us! Kibo the red panda mascot knows that speed and accuracy unlock essential momentum, but rigid memorization often creates unnecessary friction.
By mastering intuitive curriculum strategies, students transform tricky challenges into second-nature shortcuts (and help us parents remember how to navigate Tier 1 concepts in the process!).
In our Tier 1 curriculum (Kindergarten), students build foundational mastery in:
- Single-digit addition & subtraction fluency
- Making 10s regrouping strategy (Anchor to 10)
- Plus 9 Hop shortcut (+10 then subtract 1)
- Fact families within 20
Trail Trick: Making 10s
Split the smaller number to turn the bigger number into 10 first! For 8 + 5, take 2 from 5 to make 10, then add 3 to get 13!
Worked Example:
- Problem: 8 + 5
- Strategy Application: 8 + 2 = 10, then add the remaining 3!
- Solution: 13
By visualizing concepts as adaptable mental landmarks, working memory strain is significantly reduced.
Trail Pro Tip: Anchor to 10
10 is your safest mountain resting spot! Always look for ways to break numbers apart to make a clean 10 first.
