Frog-jump capitals: D, P, and B
- Students can form D, P, and B with correct stroke order and curve placement.
- Students can distinguish D from B (a classic K-1 reversal pair) by stroke origin.
Lesson plan
Warm-up
4 minLetter aerobics: review F and E with whole-body air-write, then introduce D, P, B air-writes.
- Use the verbal cues: D 'big line down, frog-jump to top, big CURVE down to the dirt-line'
- P 'big line down, frog-jump to top, little curve to the middle'
- B 'big line down, frog-jump to top, little curve to middle, little curve to bottom'
Direct instruction
10 minWatch closely — D, P, and B all start the same way. BIG LINE DOWN. FROG JUMP back to the top. Now they're different. D makes ONE BIG CURVE all the way down. P makes ONE LITTLE CURVE that stops at the middle. B makes TWO LITTLE CURVES — one to the middle, one to the bottom. (Demonstrate each on the board.) Many people get D and B mixed up — let's name the difference. D starts with the LINE, then ONE BIG belly. B starts with the LINE, then TWO little bellies. D: one big belly. B: two little bellies.
-
Notice — the line is always on the LEFT and the curve is always on the RIGHT. If you flip the curve to the left, you've made the wrong letter.model Each starts with the vertical line on the left.prompt Build D, P, B in a row with wikki stix.
-
D = one belly. B = two bellies.model Point to D. Point to B.prompt Discrimination check: teacher shows D card and B card simultaneously.
- Air-write D.
- Air-write B.
- Which has two bellies? (B)
- Where does the line go? Left or right? (LEFT)

Animation
Physical / non-image
25-second animation showing D, P, B on three-line paper in sequence. Each has green-dot start, animated stroke creation, red-dot stop. After all three are drawn, D and B appear side-by-side and a yellow circle labels D's 'one big belly' and B's 'two little bellies' — held for 5 seconds. Kindergarten-readable on-screen text. No voiceover but musical sting on each completion.
Guided practice
10 min-
Trace and form D three times.scaffold Green dot at start, red dot at stop.
-
Trace and form P three times.scaffold Same.
-
Trace and form B three times.scaffold Same; chant 'two bellies' during formation.
-
D/B sort — given a stack of upper-case D and B cards, sort into two piles.scaffold Reference card visible.
Formative assessment
2 min- Form one D and one B side by side. Circle the one with TWO bellies.
Closure
- Chant: 'D — one big belly. B — two little bellies.'
- Preview: 'Tomorrow we meet R, N, M, and H — more frog-jumps!'

Chart
Physical / non-image
8.5x11 anchor chart titled 'D or B?' Left half: large D with 'ONE big belly' label and one yellow filled-in belly shape highlighted. Right half: large B with 'TWO little bellies' label and two yellow filled-in belly shapes. Footer: 'Both have a line on the LEFT.'
Homework
5 min- Find one D and one B in your house (books, magnets, signs). Bring a drawing of where you found them.
Exercises in this lesson
Differentiation
- Tactile letters (sandpaper or wikki stix) for D-B discrimination
- Pre-traced dotted letters
- Hand-over-hand
- Try the reversal challenge: write D-B-D-B-D-B in a row
- Find D and B in the alphabet wall and identify the difference
- Translation of 'belly' if needed (everybody knows it but the metaphor may not transfer)
- Word-wall words starting with D and B that the child knows
- Use ONLY tactile letters first
- Skip B initially if confusion is severe; introduce after D and P are solid
Teacher notes
D/B reversals are normal through age 7. The point of this lesson is not to eliminate reversals (they happen) but to teach the discrimination rule so the child can self-check. Do not punish reversals; teach the rule. If a child reverses on >50% of attempts by the end of the year, flag for an OT consult and a dyslexia screener (RAN, phonological awareness battery).
