## Standard->1.MD.1 Order three objects by length; compare the lengths of two objects indirectly by using a third object.

Practice Game:

Order Objects by Length: Follow directions to choose the shortest object, longest object or order the objects by length.

Standard-> 1.MD.2 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.

Listen to the book read aloud to refresh your memory on measuring.

Practice Game:

Measure the Length of Objects: Measure the object shown using a different object.

Standard-> 1.MD.3a: Tell and write time in hours and half-hours using analog and digital clocks.

#### Watch the review video on the parts of a clock and telling time to the hour and half hour!

Practice Games:

Choose the correct time on the analog clock to match the digital clock. Create a picture with the puzzle pieces earned each turn!

Choose the correct digital time from the options below to match the analog clock.

Choose option 1: Read time to the Hour

or option 2: Read time to Hour and Half Hour

**Be sure you choose 12 hour clock. We use 12 hour clocks for am (morning) and pm (afternoon).

Standard-> 1.MD.3b Identify the days of the week, the number of days in a week, and the number of weeks in each month.

#### Watch the review video on how to use a calendar!

Standard-> 1.MD.4 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.

#### Watch the review video on how to read and use a graph!

Standard-> 1.G.1: Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes.

#### Watch the review video on the shapes and their attributes!

Standard-> 1.G.2 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.

#### Watch the review video on composing 2-D and 3-D shapes!

Standard-> 1.G.3: Partition (divide or separate) 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 (breaking down) into more equal shares creates smaller shares.

Listen to the book read aloud to refresh your memory on halves and sharing!

Practice Games:

Make a pizza while you learn about halves and fourths (quarters).

Choose which shape is divided or split into equal pieces.

Standard-> 1.NBT.1: Count to 120, starting at any number less than 120. In this range, read and write numerals (numbers) and represent a number of objects with a written numeral (number).

Watch the review video on using a 120 Chart!

Practice Game:

Use the Number Chart to practice your number knowledge from 0-99, 1-100 or 1-120! Place the missing numbers on the chart.

Standard-> 1.NBT.2 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).

Practice Game:

Shark Numbers: Choose the number shown from the base ten blocks (tens and ones).

Standard-> 1.OA.1 Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.

#### Watch the review video on adding and subtracting within 20!

Standard-> 1.OA.3 Apply properties of operations as strategies to add and subtract.3 Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)

Standard->1.OA.4 Understand subtraction as an unknown-addend problem. For example, subtract 10 – 8 by finding the number that makes 10 when added to 8.

2. Subtraction Fact Families: Press Start. (You may have to watch a 30 second AD. There's a countdown in the bottom left corner.)

Choose the related subtraction fact. Remember: SAME 3 NUMBERS

Standard-> 1.OA.5 Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).

#### Watch the review video on counting on to add!

Standard-> 1.OA.7 Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false. For example, which of the following equations are true and which are false? 6 = 6, 7 = 8 – 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.
