Dear LOR user,

Thank you for being a big part of this community. To better support the initiatives around open educational resources in the state of Michigan, all resources on the Michigan Virtual Learning Object Repository (LOR) will be moved to #GoOpen Michigan (link is external) on September 30th, 2018. After the transition, our LOR will be moved to an archived state, not allowing new user registration or new content to be added. An email with more details will be sent to registered users of the LOR. To make use of the great resources on the platform, we encourage you to create an account and add your own new resources to the #GoOpen Michigan platform (link is external).

Reason with shapes and their attributes.
Education Level: 1
Description:

Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); for a wide variety of shapes; build and draw shapes to possess defining attributes.

(1)
Reason with shapes and their attributes.
Education Level: 1
Description:

Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape. (Students do not need to learn formal names such as “right rectangular prism.”)

(0)
Reason with shapes and their attributes.
Education Level: 1
Description:

Partition circles and rectangles into two and four equal shares, describe the shares using the words halves, fourths, and quarters, and use the phrases half of, fourth of, and quarter of. Describe the whole as two of, or four of the shares. Understand for these examples that decomposing into more equal shares creates smaller shares.

(1)
Measure lengths indirectly and by iterating length units.
Education Level: 1
Description:

Order three objects by length; compare the lengths of two objects indirectly by using a third object.

(0)
Measure lengths indirectly and by iterating length units.
Education Level: 1
Description:

Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps. Limit to contexts where the object being measured is spanned by a whole number of length units with no gaps or overlaps.

(1)
Tell and write time.
Education Level: 1
Description:

Tell and write time in hours and half-hours using analog and digital clocks.

(1)
Represent and interpret data.
Education Level: 1
Description:

Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.

(1)
Extend the counting sequence.
Education Level: 1
Description:

Count to 120, starting at any number less than 120. In this range, read and write numerals and represent a number of objects with a written numeral.

(2)
Understand place value.
Education Level: 1
Description:

Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases:
-- a. 10 can be thought of as a bundle of ten ones — called a “ten.”
-- b. The numbers from 11 to 19 are composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones.
-- c. The numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two, three, four, five, six, seven, eight, or nine tens (and 0 ones).

(0)
Understand place value.
Education Level: 1
Description:

Compare two two-digit numbers based on meanings of the tens and ones digits, recording the results of comparisons with the symbols >, =, and <.

(0)
Use place value understanding and properties of operations to add and subtract.
Education Level: 1
Description:

Add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used. Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten.

(0)
Use place value understanding and properties of operations to add and subtract.
Education Level: 1
Description:

Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used.

(0)
Use place value understanding and properties of operations to add and subtract.
Education Level: 1
Description:

Subtract multiples of 10 in the range 10-90 from multiples of 10 in the range 10-90 (positive or zero differences), using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.
