Ones, Tens & Hundreds Place Value for Kids: The Complete Actionable Playbook Using Khan Academy Kids

Place value is the foundation of every math skill that follows — addition with regrouping, subtraction with borrowing, multiplication, division, and beyond. Yet it remains one of the most confusing topics for young learners. This playbook gives you everything you need to teach ones, tens, and hundreds place value effectively, using free resources from Khan Academy Kids.

Key Takeaways

• Place value is sequential: Kids must grasp ones before tens, and tens before hundreds. Never skip a stage.
• Khan Academy Kids is free and ad-free: It offers structured, research-backed lessons on place value with interactive practice perfect for ages 3–8.
• Concrete → Representational → Abstract (CRA): Hands-on manipulatives should always precede drawings, which precede symbols and numbers.
• Daily micro-sessions beat marathon study: 15 minutes per day produces stronger retention than one hour per week.
• Common pitfalls: Confusing digit value with position value and skipping visual models are the two biggest obstacles.

Understanding Place Value: Ones, Tens, and Hundreds

What Is Place Value?

Place value is the value of a digit based on its position in a number. In the number 247:

• The digit 7 is in the ones place → value = 7
• The digit 4 is in the tens place → value = 40
• The digit 2 is in the hundreds place → value = 200

Children who understand this concept can decompose and compose numbers flexibly — a critical predictor of long-term math success.

Why It Matters Early

Research from the National Council of Teachers of Mathematics shows that early place value understanding correlates strongly with third-grade math achievement. Kids who stumble here tend to fall further behind each subsequent year. Intervention at the K–2 level is both effective and cost-free when using tools like Khan Academy Kids.

The CRA Instructional Sequence for Place Value

The Concrete-Representational-Abstract framework is the gold standard for teaching mathematical concepts to young children. Follow this sequence strictly.

Phase 1: Concrete (Hands-On Manipulatives)

• Use base-ten blocks: unit cubes (ones), rods of ten (tens), and flats of one hundred (hundreds)
• Have children physically group individual cubes into bundles of ten
• Practice saying: "This rod has ten ones. It equals ten."
• Build numbers: ask the child to build 3 tens and 5 ones and then say the number (35)
• Checkpoint: Child can correctly build any number from 1–99 using base-ten blocks without prompting.

Phase 2: Representational (Drawings & Visual Models)

• Draw place-value charts with columns labeled Hundreds | Tens | Ones
• Have children draw stick figures for tens and dots for ones
• Use ten-frame drawings to show how ones fill up to make a new ten
• Transition to expanded form: 47 = 40 + 7
• Checkpoint: Child can draw a representation and correctly write the corresponding numeral.

Phase 3: Abstract (Symbols & Numbers)

• Write numbers in standard form, expanded form, and word form
• Identify digit values: "What is the value of the 6 in 62?" (Answer: 60)
• Compare numbers using >, <, = based on place value reasoning
• Introduce rounding to the nearest ten and hundred
• Checkpoint: Child fluently identifies place value of any digit in numbers up to 1,000.

Step-by-Step Action Plan

Week 1: Ones Place

• Day 1: Count objects 1–20; introduce the word ones
• Day 2: Count collections of 10+1 to 10+9; notice the pattern
• Day 3: Khan Academy Kids lesson — "Counting Objects"
• Day 4: Practice writing ones-digit numbers (1–20)
• Day 5: Game — roll two dice; add to find the ones total
• Day 6: Review and reinforce weak areas
• Day 7: Quiz — identify the ones digit in numbers 1–30

Week 2: Tens Place

• Day 1: Introduce base-ten rods; count by tens (10, 20, 30…)
