Skills Developed

  • Recognizing and naming numbers 0-10
  • Counting objects with one-to-one correspondence
  • Writing numerals 0-10
  • Comparing numbers (more, less, equal)
  • Ordering numbers from least to greatest

Phase 2: Counting & Comparing

Lessons 21-40 · 4 concepts

Phase 2 extends counting to 20, introduces number patterns, and builds fluency with number order and comparisons.

  • Understanding 'one more' and 'one less'
  • Introduction to the plus symbol

Phase 3: Addition

Lessons 41-65 · 7 concepts

Phase 3 teaches addition facts to 10 systematically, starting with +1, +2, then building to all single-digit addition.

ConceptLessonTypeExample

+245operation5 + 2 = 7
+349operation4 + 3 = 7
doubles53strategy3 + 3 = 6
+056operation5 + 0 = 5
commutative58property2 + 3 = 3 + 2
number bonds60concept5 = 2 + 3

Skills Developed

  • Adding 1, 2, and 3 to any single digit
  • Doubles facts (1+1 through 5+5)
  • Adding zero
  • Understanding the commutative property
  • Number bonds to 10
  • Solving addition equations with missing addends

Phase 4: Subtraction

Lessons 66-85 · 6 concepts

Phase 4 introduces subtraction as 'taking away' and builds the connection between addition and subtraction.

ConceptLessonTypeExample

−166operation5 − 1 = 4
−270operation7 − 2 = 5
−374operation8 − 3 = 5
fact families78concept3+4=7, 4+3=7, 7−3=4, 7−4=3
−080operation5 − 0 = 5

Skills Developed

  • Subtracting 1, 2, and 3 from numbers to 10
  • Understanding subtraction as 'taking away'
  • Connecting subtraction to addition (fact families)
  • Subtracting zero
  • Solving subtraction equations with missing numbers

Phase 5: Place Value

Lessons 86-105 · 5 concepts

Phase 5 introduces place value (tens and ones), counting to 100, and addition/subtraction within 20.

ConceptLessonTypeExample

ones86place value13 = 1 ten, 3 ones
counting to 5090number rangetwenty-one through fifty
counting to 10095number rangefifty-one through one hundred
addition to 20100operation8 + 7 = 15

  • Skip counting by 2s, 5s, and 10s
  • Adding and subtracting within 20

Phase 6: Fluency

Lessons 106-125 · 4 concepts

Phase 6 builds fluency with addition and subtraction facts to 20, introduces mental math strategies, and begins two-digit addition.

ConceptLessonTypeExample
make 10106strategy8 + 5 = 8 + 2 + 3 = 10 + 3 = 13
doubles +1110strategy6 + 7 = 6 + 6 + 1 = 13
