Number Knowledge Test
As part of the
Number Worlds
program, the Number Knowledge Test was developed to measure a student's conceptual knowledge of number sense.

1. To determine if a student is functioning at, above,
or below age/grade level in number knowledge

2. To determine which number concepts the student has mastered, which he/she is struggling with, and which he/she still needs

3. To assess a student's progress over the instructional period or academic year

4. To determine which Number Worlds level Placement Test to start testing with in order to pinpoint the program level in
which each student should begin their instruction
Test Design
Understanding the test
Age levels
The Number Knowledge Test is an oral test
that is administered individually to each
student and requires oral responses. Precise
instruction for administering and scoring
each time is included along with nine Visual
Arrays that test the solidity of a student's
understanding of number sense and decrease
the likelihood of guessing at a correct response.
Goals of the Number knowledge test
Purpose

The Number Knowledge Test was formulated to measure the conceptual knowledge of number sense that the typical child has available at the age levels of 4, 6, 8, and 10 years. Research has shown that the knowledge assessed at each age level of this test is essential for successfully learning arithmetic in school and foundational for higher mathematics learning.
The labels assigned to each level of this test (e.g., 4-year-old level) actually represent the midpoint in the range of years in which children typically acquire knowledge. They are meant to suggest that a child's understanding of number changes qualitatively every two years across the middle childhood years, becoming more complex with each change.
Levels of the test
The Number Knowledge Test is made up of four levels:

Level 0 (4-year-old level): These items assess the child's ability to count and to quantify small sets when concrete objects (counters) are available and can be touched and manipulated.

Level 1 (6-year-old level): There are two classes of items at this level: those which assess a child's knowledge of the number sequence and those that assess a child's ability to handle simple arithmetic problems.

Level 2 (8-year-old level): There are two classes of items at this level as well: those which assess knowledge of the number sequence and those that assess knowledge of arithmetic.

Level 3 (10-year-old level): This level also has two classes of items:
those which assess knowledge of the number sequence and those
that assess knowledge of arithmetic.

Requirements of the Test
The Number Knowledge Test is an oral test and is administered individually to each child and requires oral responses. Children are not allowed to use paper and pencils to answer the questions. The reason for this is that in order to measure conceptual knowledge, it is important that children figure things out in their heads.
The arithmetic items in levels 1-3 of the test include a reminder to "Assess strategy used by asking, 'How did you figure that out?'" and write it down next to the answer they gave. Doing this can aid you in determining the student's level of understanding.

The Number Knowledge Test Record includes a "Strategy" column to record the problem-solving strategy used by the student when answering arithmetic items in Levels 1-3, the most common strategies included in abbreviated form are: CU = Counting up from 1, CO = Counting on sequence, and R = Retrieval.
