Index: 4.1A Grade 3 CPI 3

 

Standard: 4.1 - Number and Numerical Operations

 

Strand: A - Number Sense

 

Cumulative Progress Indicator: 3 -  The student will identify whether any whole number is odd or even.

 

Grade: 3

 

Sample Activities:

 

·        Students use the constant function feature of their calculators to program a skip count. They press + 12 === to watch the calculator display count by twelves, trying to anticipate what number will come next and making predictions to each other. Any number can replace the 12 to change the difficulty level of the activity.

 

·        Students also use their calculators to play Guess My Rule games. One student secretly programs the calculator by typing something like x 2 =. Thereafter, every time a number is pressed followed by an equals sign, the original number will be multiplied by two. A second student must guess the rule that was programmed. Rules like + 3 =, ÷ 4 =, and - 2 = also work.

 

·        Students create and solve arrow puzzles on a hundred number chart. By naming a number and then giving directions for movement on the chart, instructions are given to arrive at some other number. For example: 72, down, down, right, right, up leaves the student at the number 84. After examples of different patterns are demonstrated on the chart, students point out patterns and try to solve puzzles mentally.

 

·        Students make a table to reflect how many handshakes there would be if everyone shook hands in groups of different sizes. For example, for 2 people, 1 handshake; for 3 people, 3 handshakes; for 4 people, 6 handshakes. As they extend the table for larger groups, the students look for a pattern in the emerging numbers.

 

·        Students search for patterns in the addition of even and odd numbers by using unifix cubes to represent the numbers and trying to arrange the sum into two stacks of equal height. (This will work for even numbers, but not for odd ones.)

 

Kidspiration Activities:

 

·        Use the number line symbol and the create SuperGrouper tool to create number line SuperGrouper shapes to order common fractions.
