Students decompose numbers less than or equal to 10 into pairs in more than one way by using objects or drawings, and they will record each decomposition by a drawing or equation (e.g. 5= 2 + 3 and 5 = 4+1).
In this activity students will demonstrate an understanding that addition is putting together. Students will show and explain with pictures, words or a number sentence that 3 plus 7 is 10 not 9. They will put together different combinations of apples and bananas to represent different addition sentences. A task card and rubric are provided. To access this task, click on the link, scroll down to the title Apples and Bananas, click on it and the task will open.
In this assessment students will solve an addition word problem three different ways. Students should have two sided bean counters to assist them with solving the problem. A rubric, student worksheet, and an assessment task sheet are provided.
The purpose of this task is for students to find different pairs of numbers that sum to 4.
The purpose of this task is for students to find different pairs of numbers that sum to 7.
The students will use 3 different color squares glued on paper to find as many combinations of numbers 10-20 as possible. This lesson was developed by NCDPI as part of the Academically and/or Intellectually Gifted Instructional Resources Project. This lesson plan has been vetted at the state level for standards alignment, AIG focus, and content accuracy.
In this assessment students will solve problems with pennies. There are five pennies in all. Some are hidden and some are not. Students will need to determine the number of pennies are under or outside the cup. Students should show 3 solutions. Teachers will need pennies or counters and cups. A rubric and assessment task sheet are provided.
Students decompose numbers less than or equal to 10 into pairs in more than one way by using objects or drawings, and they will record each decomposition by a drawing or equation (e.g. 5= 2 + 3 and 5 = 4+1).
In this interactive, students must determine how many bubbles are left under Okta's shell after some have been added or taken away.
This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: Materials * Double sided counters * Markers that are the same colors as the counters * Teacher-made “My Book of 5” (see below for detailed directions) ...
This parent guide supports parents in helping their child at home with the Kindergarten Math content.
This resource accompanies our Rethink Kindergarten Math Operations & Algebraic Thinking unit. It includes ideas for use, ways to support exceptional children, ways to extend learning, digital resources and tools, tips for supporting English Language Learners and students with visual and hearing impairments. There are also ideas for offline learning.
This unit was created by the Rethink Education Content Development Team. This course is aligned to the NC Standards for Kindergarten Math for Operations in Algebraic Thinking.
In this lesson, students will use circular and scattered dot configurations of the numbers 3, 4, and 5 to find hidden partners.
In this lesson, students will model decompositions of 3 with materials, drawings, and expressions. They will also represent the decomposition as 1+2 and 2+1.
In this lesson, students write numerals 1-3 and represent decompositions with materials, drawings, and equations, 3=2+1 and 3=1+2.
In this lesson, students model composition and decomposition of numbers to 5 using actions, objects, and drawings.
In this lesson, students will model composition and decomposition of numbers to 5 using fingers and linking cube sticks.
In this lesson, students represent composition story situations with drawings using numeric number bonds.
In this lesson, students represent decomposition story situations with drawings using numeric number bonds.
