Ten Frame Model
Anchor to Five!
Choral Chant: Say the Equation!
Case A: 5 on Top + 3 Below
5 + 3 = 8
Full top row is 5... count on: 6, 7, 8!
Case B: 6 on Left + 2 on Right
6 + 2 = 8
Start at 6... add 2 more = 8!
Teacher Cue: "Look at the top row! How many to make 5? How many below?"
Five-Structure Rule
Ten Frame Model
Friends of 10!
Fill the Entire Frame!
7 Dots + 3 Missing Spaces
7 + 3 = 10
3 empty spots filled = exactly 10!
4 Dots + 6 Missing Spaces
4 + 6 = 10
Turnaround fact: 6 + 4 is also 10!
Quick Quiz: If you see 8 dots in a ten frame, how many empty spaces are left?
Say: 2!
Domino Model
Domino Dot Detectives
Subitize & Add!
Double Fact! Same on Both Sides
4 + 4 = 8
Spot 4 instantly: double 4 is 8!
5 Dots + 3 Dots
5 + 3 = 8
Same sum as 4 + 4 = 8! Different domino parts.
Look & Snap: Notice how 5 dots looks like an "X" pattern!

Subitizing & Model Diagnostics
Ten Frame Subitizing: Ensure students recognize a complete top row as 5 automatically without counting individual dots 1 by 1. Practice quick flashing: "See 5, then count on!"
Domino Dot Patterns: Check that students subitize familiar patterns (like 4 corners and 5 X-pattern). For doubles (4+4), encourage instant recall rather than recount.
Differentiation Strategies
Support / Intervention: Provide real foam dominoes and ten frame mats with two-color red/yellow counters so students can manipulate objects directly before drawing.
Extension / Challenge: Have students draw their own domino with two different numbers that add to 10 (e.g., 6 and 4) and write the turnaround equation (4 + 6 = 10).
