- Tell time on analog and digital clocks.
- Read and interpret different types of graphs

__Grade 2__

- Read, write, and model numbers up to 10,000, and identify place values in these numbers.
- Collect and organize data to create charts, tables, graphs, and line plots.
- Measure length to the nearest inch and centimeter.
- Read, write, and explain expressions and number sentence using the symbols +, -, =, > and <.
- Demonstrate automaticity with all addition facts through 10 + 10 and fluency with the related subtraction facts.
- Use manipulatives, number grids, and tally marks to solve problems involving the addition and subtraction of multi-digit whole numbers.

__Grade 3__

- Relate math to real world situations and use the language of mathematics to clearly communicate ideas.
- Demonstrate an understanding of place value with seven digits.
- Read, write, and explain expressions and number sentence using the symbols +, -, =, x, /, > and <.
- Demonstrate proficiency with addition and subtraction with regrouping.
- Understand Commutative and Associative Property of Addition and Multiplication.
- Use repeated addition, arrays, and knowledge of products and factors to solve multiplication problems.
- Show and solve division problems with remainders.
- Identify and show fractional parts, work with equivalent fractions, estimate and compare fractions.
- Show symbolic representations for denominations of money and understand decimals with money.
- Work with estimation and recognize when it’s appropriate.
- Collect, organize and describe data and make decisions and predictions based on data.
- Construct, read and interpret charts, diagrams, and graphs.
- Understand the concepts of probability and chance, and use fractions to represent probability and statistics.
- Recognize and draw parallel, intersecting and perpendicular lines, lines of symmetry, and different angles.
- Calculate area and perimeter.
- Show and calculate time (elapsed).

__Grade 4__

- Read, write, and compare multi-digit whole numbers using base-ten numerals, number names, and expanded form.
- Fluently add and subtract whole numbers up to 1 million.
- Round multi-digit whole numbers to any place.
- Use mental computation and estimation strategies such as rounding to assess the reasonableness of answers.
- Understand factors and multiples and find all factor pairs for a whole number between 1-100.
- Multiply or divide whole numbers with and without remainders, and represent the problem using equations, rectangular arrays, area models, and/or the relationship between multiplication and division.
- Recognize equivalent fraction by using visual fraction models; compare two fractions by creating common denominators or numerators or by comparing to a benchmark fraction such as 1/2.
- Add and subtract fractions and mixed numbers with like denominators and multiply a fraction by a whole number by using visual fraction models and equations.
- Express a fraction with denominator 10 as an equivalent fraction with denominator 100; write fractions with denominators of 10 or 100 as decimals.
- Compare two decimals to hundredths place by reasoning about their size.
- Understand the relative sizes of measurement units, and use the four operations to solve problems involving measurement and conversion of measurements (distances, intervals of time, liquid volumes, masses of objects, and money).
- Apply the area and perimeter formulas for rectangles, irregular polygons, circles, and triangles in real world and mathematical problems.
- Draw and identify lines and angles, classify shapes by properties of their lines and angles, and recognize a line of symmetry for a two-dimensional figure.
- Understand concepts of angle measurement; measure and sketch angles in degrees using a protractor.
