### Math Continuum Quarter 1

Kindergarten Math Quarter 1

K.NS.1: Count to at least 100 by ones and tens and count on by one from any number

Count Around is an activity that can be used to help students with counting and counting on. Have the students sit in a circle. Then, toss a soft ball to one of the students and have them pick a number from 0-20. Next, that student tosses the ball to a different student and the student that catches the ball says the number that comes next. Continue play until everyone has had a chance to catch the ball at least once. Encourage students to think of the number that comes next even if they are not the ones to catching the ball. [There are variations to this activity, such as, starting from 0, count by tens with each toss of the ball.]

K.NS.2b Represent a number of objects with a written numeral 0-20 (with 0 representing a count of no objects).

Practice Activity: Have students pick nine numbers from 0-10 and place them on a Bingo card like below. Then, show students a number word, such as “five”, and have them mark that on their Bingo card if they used the number 5. Continue play until someone wins. [A variation of this is to have students pick nine numbers from 0-20 and place them on their Bingo card. Then, show students a picture of a number of objects and have them mark that number on their card if they used that number.]

K.DA.1: Identify, sort, and classify objects by size, number, and other attributes.  Identify objects that do not belong to a particular group and explain the reasoning used.

Provide a bag with different objects for each student or groups of students. For example, a bag might have 4 red counters, 6 blue counters, and 7 yellow counters. Have the students sort the objects by color. Then, have them arrange them in order from least to most (i.e. red, then blue, then yellow).

3.DA.1: Create scaled picture graphs, scaled bar graphs, and frequency tables to represent a data set—including data collected through observations, surveys, and experiments—with several categories.  Solve one- and two-step “how many more” and “how many less” problems regarding the data and make predictions based on the data.

Activity: Students can conduct an observation, survey, or experiment. They can collect, organize, and display their data, and make observations based on their data display. (Examples: conduct a survey about favorite food, color, etc.; observe and tally the different colors of shirts classmates wear to school on a given day.)

4.AT.1: Solve real-world problems involving addition and subtraction of multi-digit whole numbers (e.g., by using drawings and equations with a symbol for the unknown number to represent the problem).

How many more cards does Julie have than Milagro and Carl combined?

b) Barry and Tina participated in a reading contest last year. They read a combined total of 12,082 pages. Barry read 5,916 pages. How many pages did Tina read?

No Unit Assessments

6.NS.1: Understand that positive and negative numbers are used to describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level, credits/debits, positive/negative electric charge).  Use positive and negative numbers to represent and compare quantities in real-world contexts, explaining the meaning of 0 in each situation.

A submarine was situated 400 feet below sea level. If it ascends 250 feet, what is its new position? Represent this situation on a number line. What does 0 represent in this situation?
