### Decompose Numbers 11 to 19

This Numbers and Operations in Base Ten lesson focuses on decomposing numbers 11 to 19. As prerequisites, students should be able to write numbers from 0 to 20 (K.CC.3), and understand the relationship between numbers and quantities (K.CC.4). The lesson includes research-based strategies and strategic questions that prepare students for assessments.

### Compare the Length of Objects

This Measurement and Data lesson practices comparing the length of objects. The lesson includes research-based strategies and strategic questions that prepare students for assessments. Review of the animation on the Concept Development pages prior to the lesson will be helpful, as it is meant to be read aloud. Manipulatives should be used as examples of longer, shorter, etc. Flashcards are provided as an extra resource.

### Compare the Weight of Objects

This Measurement and Data lesson compares the weight of objects. The lesson includes research-based strategies and strategic questions that prepare students for assessments. Various objects within the classroom can be used as demonstrations. Please review the animation on the Concept Development page. Animated text is intended to be read aloud by the teacher. Also, note that this lesson does not cover any form of density. All comparisons are being made between objects with similar densities. It would be worthwhile to separately cover the idea that some things may be small but heavy (a stapler, a textbook, etc.) while others are large and light (empty boxes, Styrofoam, etc.).

### Compare the Capacity of Objects

This measurement and geometry lesson focuses on comparing the capacity of objects. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students look at two photos of objects. Then, they point to the object that holds more and circle it. Finally, they cross out the object that holds less. In addition to the lesson, there are eight pages of Independent Practice and review modeled on current adaptive testing items.

### Identify Days of the Week

This measurement and geometry lesson focuses on identifying the days of the week, using yesterday, today, and tomorrow with the days of the week. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, the teacher reads a problem, such as "Pretend today is Monday. What day was yesterday?" The student then circles the correct day of the week. In addition to the lesson, there are four pages of Independent Practice and review modeled on current adaptive testing items.

### Use Clocks to Tell Time

This measurement and geometry lesson focuses on using clocks to tell time. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, the students look at a photo of two analog clocks and one digital clock. By looking at the short hand on the analog clocks they have to match it to the same time on the digital clock. In addition to the lesson, there are eight pages of Independent Practice and review modeled on current adaptive testing items.

### Name the Days of the Week

This measurement and geometry lesson focuses on naming the days of the week. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, the students track with the teacher in reading the days in sequence. Then, they identify a day of the week that is missing, if any. In addition to the lesson, there are four pages of Independent Practice and review modeled on current adaptive testing items.

### Identify the Time of Everyday Events

This measurement and geometry lesson focuses on identifying the time of everyday events. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, the students look at a picture of an event and then think about when that event happens during the day. Finally, they find each time in the timeline and identify the correct time on a choice of digital clocks. In addition to the lesson, there are eight pages of Independent Practice and review modeled on current adaptive testing items.

### Describe the Position of an Object

This Geometry lesson practices describing the position of an object (such as above, below, beside, in front of, behind, and next to). It is recommended that manipulatives are used in demonstration. The lesson includes research-based strategies and strategic questions that prepare students for assessments.

### Name Shapes

(A) Identify two-dimensional shapes, including circles, triangles, rectangles, and squares as special rectangles

K.6.D(D) Identify attributes of two-dimensional shapes using informal and formal geometric language interchangeably

K.6.E(E) Classify and sort a variety of regular and irregular two- and three-dimensional figures regardless of orientation or size

This Geometry lesson practices naming shapes. The lesson includes research-based strategies and strategic questions that prepare students for assessments. This lesson contains a Concept Development and Skill Development/Guided Practice for each shape. The lesson is meant to discuss the attributes of each shape, one at a time until students are able to recognize each of the shapes and name them based on their attributes. Flashcards are available for this lesson.

### Identify Objects That Do Not Belong

This algebra and functions lesson focuses on identifying objects that do not belong. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, the teacher names the objects in a group of pictures. Students cross out the object that is not like the others. Finally, they say which object does not belong. In addition to the lesson, there are four pages of Independent Practice and review modeled on current adaptive testing items.

### Describe Plane Objects

This measurement and geometry lesson focuses on describing plane objects. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, the students look at a picture of a plane object. Then, they write the number of sides and the number of corners for each plane object. In addition to the lesson, there are four pages of Independent Practice and review modeled on current adaptive testing items.

### Compare Plane and Solid Objects

This measurement and geometry lesson focuses on comparing plane and solid objects. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, the students look at a picture of a plane object and compare it to a solid object that looks like the plane object. Then, they write the number of sides and the number of corners for each plane object. In addition to the lesson, there are five pages of Independent Practice and review modeled on current adaptive testing items.

### Extend Patterns

This statistics, data analysis, and probability lesson focuses on extending patterns. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, the students read the pattern of shapes aloud. Then, they identify the shape that comes next and circle it. In addition to the lesson, there are four pages of Independent Practice and review modeled on current adaptive testing items.

### Kindergarten Next Generation Science Standards Learning Objectives & Essential Tools

Standards are often confused with being Learning Objectives. Standards are the content and skills students need to know by the end of a school year. Learning Objectives are the content and skills students need to know by the end of a lesson. Our Next Generation Science Standards Learning Objectives & Essential Tools guides display teachable Learning Objectives alongside the standards for easy reference. Here on Educeri, the guide also links to relevant lessons right here on the site, making finding a lesson easy. As we add more lessons, we will be updating this guide, so check back regularly.
