QUESTION 1: PRE-NUMBER CONCEPTS (25) Read the statement below and answer
the questions that follow. From birth already, children are exposed to mathematical
concepts and activities. For example, when feeding a baby, a mother measures the
formula in millilitres; during bath times, nursery rhym...
1. One-to-One Correspondence: This refers to the ability to match each object in a
set with one unique counterpart in another set. This concept lays the groundwork for
understanding counting and ensures that children recognize the relationship
between quantities. By developing one-to-one correspondence, children begin to
understand that numbers represent quantities, which is essential for later arithmetic.
2. Comparison: Comparison involves determining which of two or more quantities is
greater, lesser, or equal. This foundational skill helps children understand
relationships between different sets of numbers. By comparing, children can make
sense of larger and smaller numbers and develop an intuition for ordering.
3. Conservation: Conservation is the understanding that quantity remains the same
despite changes in shape or arrangement. This concept is vital to number
understanding, as it enables children to grasp that numbers are stable and not
altered by visual changes. For example, recognizing that a row of five objects is still
five even if they are spaced apart is key to solidifying their concept of number
permanence.
4. Ordering: Ordering involves arranging items based on a characteristic, such as size
or quantity. This concept not only enhances counting skills but also helps children
understand sequences and patterns, which are critical in mathematical reasoning.
5. Subitising: Subitising is the ability to instantly recognize the quantity of a small
group of objects without counting. This skill aids in developing a sense of number
and enhances mathematical fluency. Subitising fosters rapid recognition, allowing
children to make quick numerical judgments and build their overall confidence in
mathematical contexts.

1. One-to-One Correspondence: Use counting objects such as blocks or beads,
encouraging children to match each object to a number card while counting aloud
(e.g., one block per number).
2. Comparison: Engage children with two sets of objects (e.g., shells and pebbles) and
ask them which set has more. Discuss the characteristics that make one set larger or
smaller.
3. Conservation: Present children with two equal rows of counters, then spread one
row out and ask if they still have the same amount. This activity fosters discussion
about quantity versus spatial arrangement.
4. Ordering: Provide children with a selection of colored blocks and ask them to
arrange them from smallest to largest. This activity enhances their understanding of
numerals and size differences.
