2.7B 2-2D and 2-3D figures and how they are alike and different

2.7  the student uses attributes to identify 2 and 3 dimensional geometric figures.  The student compares and contrasts 2 and 2 dimensional geometric figures or both
1	2	3
1.6a  describe and identify 2D geo figures, including circles, triangles, rectangles, and squares (a special type of rectangle) 1.6b  describe and identify 3D geo figures, including spheres, rectangular prisms (including cubes), cylinders and cones	2.7b  use attributes to describe how 2-2D figures or 2-3D figures are alike or different	3.8  the student uses formal geometric vocabulary.  The student is expected to identify, classify, and describe 2D figures, 3D figures, or both by their attributes.
use attributes to describe how 2-2D figures or 3-2D figures are alike or different                                                   use—to employ for some purpose; put into service; make use of describe—to give an account of in words; to tell in words what something or someone is like

Activities:

• Use a double bubble map to compare 2-2D or 2-3D figures
• Model using correct vocabulary (face, edge, vertices, sides, base) when comparing and contrasting
• Use manipulateives to physically touch the attributes while comparing

good math writing activity to use with 2D and 3D shapes

2.2 A Fractions

2.2  the student describes how fractions are used to name parts of a whole object or sets of objects
1	2	3
1.2A  separate a whole into two, three, or four equal parts and use appropriate language to describe the parts such as “three out of 4 equal parts” 1.2B  use appropriate language to describe part of a set such as “three out of the eight crayons are red”	2.2A  use concrete models to represent and name fractional parts of a whole object (with denominators of less); (only fractions of a whole at this time)	3.2B  compare fractional parts of whole objects or sets of objects in a problem situation using concrete models
Use concrete models to represent  and name fractional parts of a whole object

Activities:

• Use 10 to 12 different color pom poms to represent a whole caterpillar.  Then Write fractions for three different colors in sentence format and numerator over denominator format.

2.3C addition and subtraction--addition regrouping

2.3 Number, operation, and quantitative reasoning. The student adds and subtracts whole numbers to solve problems.
1	2	3
1.3B Use concrete and pictorial models to apply basic addition and subtraction facts (up to 9+9=18 and 18-9=9)	2.3 C select addition or subtraction to solve problems using two-digit numbers, whether or not regrouping is necessary (addition and subtraction at this time---addition with regrouping at this time)	3.3B Select addition or subtraction and use the operation to solve problems involving whole numbers through 999
Select addition to solve problems using two-digit numbers, whether or not regrouping is necessary Select subtraction to solve problems using two-digit numbers, whether or not regrouping is necessary Select - to choose in preference to another or others; pick out Solve - to work out the answer or solution to (a mathematical problem)

Activities:

• begin solving word problems only using the numbers needed - no extra information
• begin with only 1 step problems
• display answer choices in words

Possible Test Questions:

2.8 Number Line

2.8 The student recognizes that a line can be used to represent a set of numbers and its properties.  The student is expected to use whole number to locate and name points on a number line.

1.7 G Compare and order two or more objects according to temperature (from hottest to coldest)	2.8 The student recognizes that a line can be used to represent a set of numbers and its properties.  The student is expected to use whole number to locate and name points on a number line.	3.12 use a thermometer to measure temperature
recognizes that a line can be used to represent a set of numbers recognizes that a line can be used to represent its properties use whole numbers to locate points on a number line use whole numbers to name points on a number line recognizes - to identify as something previously seen, known, etc.                       to identify from knowledge of appearance or characteristics use—to employ for some purpose; put into service; make use of

Activities:

• Create a human number line and manipulate who comes before, who comes after, or between
• Students make their own number line by cutting a 100 chart
• fill in missing numbers on a number line during calendar
• asking question such as "What number is 2 greater than 81?"
• Have students take out a text book and ask them to find a page number.  If the number is close to 1 they should look in the front of the book.  If the number is larger, they should look towards the end of the book.
