About the Math

Students view counting as a mechanism used to land on a number. Young students mimic counting often with initial lack of purpose or meaning. Coordinating the number words, touching or moving objects in a one-to-one correspondence may be little more than a matching activity. However, saying number words as a chant or a rote procedure plays a part in students constructing meaning for the conceptual idea of counting. They will learn how to count before they understand cardinality, i.e. that the last count word is the amount of the set.

Progression of Standard within Kindergarten

This progression informs how to develop the standard within the grade level. This progression is provided by HCPSS Elementary Mathematics.

Quarter 1	Quarter 2	Quarter 3	Quarter 4
Count to 10 by ones. Count to 20 by ones.	Count to 50 by ones.		Count to 100 by ones. Count to 100 by tens.

Lesson Seeds (Prompts for Rigor)

Rigorous mathematics instruction balances the teaching and learning of conceptual understanding, procedural understanding, and the application of mathematics standards. Below are prompts for applying rigor in your classroom. They may support small group instruction or whole group collaborative investigations. They are intended to serve as a starting point for planning. See the Increasing Rigor page for more information.

Count backwards from 100 by 10s and 1s
Count forwards and backwards from any given number to 100.

Give students a blank fifty chart have them fill the chart in starting at 28 and ending at 46.
Give students a blank hundred chart with the number 54 filled in. Ask students to work backwards from 54, completing the chart until they reach 12 and stop.
Give students a completed hundred chart that is cut up into six, seven or eight sections. Have them put it back together and justify the puzzle placements.
Draw a number line with the endpoints of 0 and 100. Place a dot on the number line. What number on the number line does the dot represent? How do you know?

Learning Targets

conceptrubric

Count to 10 by ones.
Count to 20 by ones.
Count to 100 by ones.
Count to 100 by tens.

Learning targets identify what students should be able to do. The resources below can be used to measure student understanding of the standard. The recording sheet can be used to collect data. The rubrics can be applied to any task. Select the preview icon to preview any document before downloading.

Common Misconceptions

Some students might not see zero as a number. Ask students to write 0 and use zero to represent the number of items left when all items have been taken away. Avoid using the word none to represent this situation. When counting over decades, students may say, "Twenty-eight, twenty-nine, twenty-ten". They are following the sequence from 1 to 10. Use a fifty or hundreds chart so students can see the progression of the numbers.
