• Count from 1-100 by ones
• Count from 1-100 by tens
• Count backward from 31-1
• Count from 1-100 by tens and fives
• Write numbers from 1-100

• Write, generate, and illustrate number words zero through twenty
• Identify, explain, and demonstrate the place value of numbers
• Identify and show the fractions of halves, thirds, fourths, fifths, and sixths
• Use the correct sign when comparing numbers or concrete objects, < or >

Your first grade student will explain, model, and demonstrate the meaning of addition and subtraction with whole numbers by:

• Writing number sentences using the symbols of -, +, or =
• Using the correct sign or symbol when comparing facts
• Generating, adding, and subtracting fact families up to 20
• Explaining the relationship between addition and subtraction as inverse operations by using numbers up to 20

• Using addition and subtraction to solve real world problems
• Adding and subtracting two-digit numbers without regrouping
• Adding and subtracting three-digit numbers without regrouping
• Estimating and recognizing reasonable answers in three-digit whole number addition and subtraction problems with no regrouping
• Identifying the correct amount of money required to buy an object
• Adding and subtracting using pennies, nickels, dimes, and quarters
• Solving word problems using money
• Estimating the amount of change
• Using ordinal numbers

Your first grade student will come to understand patterns and methods of classification by:

• Sorting concrete objects by color, size, and shape
• Sorting concrete objects by two and three criteria
• Identifying measurable changes that are predictable, e.g., students grow taller, not shorter, as they get older
• Finding, extending, and creating patterns with concrete objects, pictures, numbers, and fact families

Your first grade student will work with two- and three-dimensional shapes by:

• Identifying two- and three-dimensional shapes
• Identifying two-dimensional shapes in three-dimensional shapes
• Putting at least two shapes together to form a new shape
• Making a picture using at least four different shapes
• Describing and naming the direction and distance in navigating space using spatial and cardinal words
• Recognizing and exploring symmetry
• Identifying and determining whether two-dimensional shapes are congruent (same shape and size) or similar (same shape different size)

Your first grade student will use standard and non-standard units of measure by:

• Measuring objects with standard units and non- standard units of measure such as paper clips, straws, blocks, etc.
• Recognizing rulers that show both inches and centimeters
• Using scales to measure weight

• Identifying analog and digital clocks and their parts
• Recognizing the difference between day and night

• Estimating the passage of time
• Putting events of a day in sequential order according to time
• Estimating and measuring the height, weight, and length of objects

Your first grade student will collect, sort, represent, and analyze data by:

• Tallying data and creating line, bar, and picture graphs
• Comparing and contrasting the similarities and differences of weather, people, animals, and objects
• Constructing questions that can be answered by using information from a graph or a table
• Describing events related to the student’s experiences as more or less likely to happen
• Reading and interpreting graphs and tables to make comparisons and predictions
