Number and Operations
1. Demonstrate concepts of number sense by using multiple representations of whole numbers up to 1000, counting forward and backward by threes from a given number, identifying a number that is 100 more or 100 less than a given number, and differentiating between odd and even numbers. (Counting Squares , Odd or Even , Skip Counting )• Identifying position using ordinal numbers to 100th
• Determining the value of a digit in the ones, tens, hundreds, and thousands place (Place Value to 1000 )
• Determining the value of a number expressed in expanded notation (Place Value to 1000 )
2. Apply the operations of addition and subtraction to solve problems involving two-digit numerals, using multiple strategies with and without regrouping. (Long Addition to 1000 , Basic Addition to 1000 , Basic Subtraction to 1000 , Long Subtraction to 1000 )
• Demonstrating computational fluency for basic addition and subtraction facts with sums through 18 and differences with minuends through 18, using horizontal and vertical forms (Fast Addition , Fast Addition Reverse , Fast Subtraction , Missing Term , Mixed Addition and Subtraction )

• Identifying line symmetry in plane geometric figures
• Creating designs that exhibit line symmetry
• Recognizing the results of changing the position (transformation) of objects or shapes by sliding (translation), turning (rotation), or flipping (reflection)
9. Describe the route from one location to another by applying concepts of direction and distance.
• Following multistep directions to locate objects
• Reading maps of the school environment
• Using grids for movement between points
Measurement
10. Measure length in customary units, including inches, feet, and yards.• Using metric units
• Using appropriate tools, including rulers, yard sticks, meter sticks, or tape measures
11. Estimate weight and capacity by making comparisons with familiar objects.
12. Tell time to the minute using analog and digital clocks. (Telling Time )
Data Analysis and Probability
13. Create displays, including appropriate labels, for a given set of data using pictographs, tally charts, bar graphs, or single- or double-loop Venn diagrams.• Interpreting graphic displays (Tally and Pictographs , Bar Graphs )
14. Determine if one event related to everyday life is more likely or less likely to occur than another event.
