Which activity would best help a student understand place value and write numerals?

• A. Arranging groups of base 10 blocks and writing the numerals represented
• B. Counting aloud while jumping on a number line
• C. Using a calculator to compute sums
• D. Reciting numbers from memory

Answer: (A)

Understanding place value means seeing that a digit’s position tells you how many tens and ones (and hundreds, if you’re at a higher level) are represented, and connecting that meaning to how we write the number. Using base-10 blocks lets a student physically group ten ones into a ten and see how those tens combine with ones to form a number; writing the numeral while handling the blocks reinforces that two tens and three ones become the written symbol 23. This concrete-to-symbol connection is exactly what builds a solid grasp of place value.

Counting aloud on a number line helps with fluency and order but doesn’t show how digits carry different magnitudes in each place. A calculator bypasses the need to manipulate quantities or form the numeral. Reciting numbers from memory doesn’t link quantity to the written form either.
