Question 1

A kindergartner counts a set of 6 blocks and, when asked 'How many?', recounts all of them. Which counting principle has the child not yet mastered?

Cardinality

Answer

Cardinality is understanding that the last number said tells how many are in the whole set.

Question 2

Which activity best builds subitizing skills in early learners?

Accepted Answer

Briefly flashing dot cards and asking how many dots were seen

Answer

Subitizing is instantly recognizing small quantities without counting, which quick dot-card flashes develop.

Question 3

A teacher reads a story problem aloud and students struggle with the word 'altogether.' What is the most appropriate instructional response?

Accepted Answer

Explicitly teach the meaning of the term using concrete models and context

Answer

Explicit vocabulary instruction in context builds understanding rather than reliance on unreliable keyword tricks.

Accepted Answer

Base-ten blocks, then drawings of blocks, then numerals and symbols

CRA moves from hands-on objects to pictures to symbolic notation.

A student solves 8 + 5 by thinking '8 + 2 = 10, then 3 more is 13.' Which strategy is this?
