Counting from 0 to 120

Counting in sequence from 0 to 120 helps children build strong number sense. Students should practice saying each number in order and recognize the pattern as numbers grow larger.

Counting Activities:
  • Count aloud together from 0 to 50, then continue to 120.
  • Use a hundred chart to point and read numbers up to 120.
  • Ask: “Can you start at 35 and count up to 55 without skipping?”
Teaching Tip

Encourage students to use finger-pointing or number charts to stay in sequence and avoid skipping numbers.

Grouping Numbers with Blocks

Using blocks to model numbers helps children understand place value. Groups of ten blocks represent tens, while single blocks represent ones. Numbers up to 120 can be shown using at most 10 blocks in a group.

Block Model Practice:
  • Show 42 as 4 groups of ten blocks and 2 single blocks.
  • Ask: “How many tens and ones are in 87?”
  • Build 100 using 10 groups of ten blocks.
Helpful Strategy

Remind students that grouping makes counting easier. Count tens first, then ones, to find the total number.

Reading and Writing Numbers

Reading and writing numbers reinforces the connection between spoken numbers, written numerals, and quantities. Students should practice writing numbers up to 120 clearly and correctly.

Writing Practice:
  • Trace and write numbers from 1 to 50 with proper numeral formation.
  • Say a number aloud (for example, 76) and have students write it on paper.
  • Draw block models and write the matching numeral beside them.
Instructional Focus

Emphasize correct numeral formation from the top down. Pair written numbers with visual models to strengthen understanding.

Comparing and Ordering Numbers

Comparing numbers helps children decide which is greater, less, or equal. Ordering numbers builds understanding of number patterns and relationships up to 120.

Comparison Activities:
  • Compare 56 and 62 → “Which is greater?”
  • Place 43, 29, and 51 in order from least to greatest.
  • Ask: “Are 70 and 70 equal?”
Visual Strategy

Use number lines and block models side by side to compare numbers quickly and accurately.

Building Counting Fluency

Fluency means counting forward, backward, and by groups with ease. Practicing with numbers up to 120 helps students gain speed and confidence in their number skills.

Fluency Practice:
  • Count forward from 0 to 120 by ones.
  • Count backward from 30 to 0.
  • Practice skip counting by 5s and 10s up to 120.
Instructional Reminder

Keep practice sessions short and engaging. Encourage students to repeat difficult sections to build accuracy and speed.
