Explanation: In first grade, students build foundational number skills. They learn to count, read, and write numbers up to 120, understand place value, compare numbers, and identify patterns.
Count to 120 starting from any number
Read and write numbers up to 120
Understand place value (ones and tens)
Compare two-digit numbers using >, <, and =
Count forward and backward by 1s, 5s, and 10s
Identify even and odd numbers (introductory)
Explanation: In Grade 1, students understand addition as putting together and adding to. They use objects, drawings, and equations to add numbers within 20. Strategies like counting on, making 10, and doubles help solve addition problems. Number lines are also used to visualize addition, and students practice solving word problems using addition.
Understand addition as putting together and adding to
Use objects, drawings, and equations to add
Add within 20 using strategies (counting on, making 10, doubles)
Use a number line for addition
Solve word problems using addition
Explanation: In Grade 1, students learn subtraction as taking apart and taking from. They use objects, drawings, and equations to subtract numbers within 20. Strategies such as counting back and using fact families help students subtract. Number lines are used to visualize subtraction, and word problems strengthen understanding of subtraction concepts.
Understand subtraction as taking apart and taking from
Use objects, drawings, and equations to subtract
Subtract within 20 using strategies (counting back, fact families)
Use a number line for subtraction
Solve word problems using subtraction
Explanation: Students learn the relationship between addition and subtraction. They use fact families to understand how numbers are connected, for example, 6 + 4 = 10 and 10 - 4 = 6. They also practice determining missing numbers in addition and subtraction equations to deepen their understanding.
Understand the relationship between addition and subtraction
Use fact families (e.g., 6 + 4 = 10, 10 - 4 = 6)
Determine missing numbers in addition/subtraction equations
Explanation: In Grade 1, students group objects into tens and ones to understand the value of digits in two-digit numbers. They learn to compare two-digit numbers based on place value to identify which number is greater or smaller.
Group objects into tens and ones
Understand the value of digits in 2-digit numbers
Compare two-digit numbers based on place value
Explanation: Students practice skip counting by 2s, 5s, and 10s to develop fluency with number sequences. They learn to recognize patterns in numbers, including identifying odd and even numbers, and fill in missing numbers in sequences to build number sense and pattern recognition skills.
Skip count by 2s, 5s, and 10s
Recognize patterns in numbers (e.g., odd/even, sequences)
Fill in missing numbers in a number sequence
Explanation: Students learn to compare lengths of objects using terms like longer/shorter and taller/shorter. They practice measuring with non-standard units such as paper clips or blocks. Additionally, they learn to tell and write time to the hour and half-hour using both analog and digital clocks.
Compare lengths of objects (longer/shorter, taller/shorter)
Measure using non-standard units (paper clips, blocks)
Tell and write time to the hour and half-hour using analog and digital clocks
Explanation: Students learn to identify and name common 2D shapes such as circles, squares, triangles, rectangles, and hexagons. They also identify 3D shapes like cubes, spheres, cones, and cylinders. They describe shape attributes including sides, vertices, and faces, and practice composing and decomposing shapes to create new shapes.
Identify and name 2D shapes (circle, square, triangle, rectangle, hexagon)
Identify and name 3D shapes (cube, sphere, cone, cylinder)
Describe attributes of shapes (sides, vertices, faces)
Compose and decompose shapes to form other shapes
Explanation: Students learn to sort and classify objects into different categories based on attributes such as color, shape, or size. They create simple picture graphs and bar graphs to organize information visually and practice interpreting information from these graphs to answer questions.
Sort and classify objects into categories
Create simple picture graphs and bar graphs
Interpret information from graphs
Explanation: Students learn to identify common coins such as pennies, nickels, dimes, and quarters. They understand the value of each coin and practice counting collections of coins up to one dollar. This foundational money knowledge helps students recognize coins and their worth in everyday situations.
Identify coins (penny, nickel, dime, quarter)
Understand the value of coins
Count collections of coins (within $1, introductory)
