Multi-Digit Computation Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used. What are some strategies and activities you use to develop this standards?

Sample Assessment Item 1 Show the student 14 cubes. Say: There are 14 cubes here. What if we added ten more cubes? How many would we have? How did you figure that out? Pause. Then, say: Let’s pretend we have 24 cubes. What if we added ten more cubes? How many would we have? What if we added ten more cubes? How many would we have?

Sample Assessment Item 1 Pause. Then, say: Let’s pretend we have 89 cubes and we took ten away. How many would we have? What if we took away ten more cubes? How many would we have?

Sample Assessment Item 2 Say: I’m going to show you a number. I want you to tell me the number, and then tell me what 10 more than that number is quickly, without counting if you can. Let’s practice with this card. Show card #1 (20). Say: What is this number? Once the student responds say: What is ten more than this number?

Sample Assessment Item 2 Then say: Now I’m going to show you a number. I want you to tell me the number, and then tell me what 10 LESS than that number is quickly, without counting if you can. Let’s practice with this card. Show card #6 (30). Say: What is this number? Once the student responds say: What is ten less than this number?

Multi-Digit Addition 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.

Geometry 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.

Geometry 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.
