Second Grade Readiness Checklist - First Grade Mathematics

As you reach the end of first grade, you might be wondering: "Am I ready for second grade math?" Second grade is a wonderful year where numbers get larger, addition and subtraction strategies go deeper, and geometric reasoning expands. The best way to enter second grade with confidence is to review the core benchmarks of first grade mathematics. This checklist is your personal passport: read through each milestone, celebrate the skills you have mastered, and identify any areas you want to practice over the summer.

Domain 1: Operations and Algebraic Thinking

These skills form the engine of your arithmetic power:

Operations Mastery Checklist:
[ ] I can add and subtract within 20 using strategies like counting on, doubles, and making 10.
[ ] I can solve word problems (Result Unknown, Change Unknown, Start Unknown) within 20.
[ ] I can add three single-digit numbers by finding friendly pairs that make 10.
[ ] I understand that the equal sign (=) means balance, and can identify true/false equations.
[ ] I can find the missing number in equations like 7 + ? = 15.

Self-Check Reflection

Can you solve 8 + 7 in your head in less than three seconds? Can you explain why 8 + 7 = 15 using near doubles (7 + 7 = 14, plus 1 is 15)? If so, your addition engine is running smoothly!

Domain 2: Number and Operations in Base Ten

These skills ensure you understand how big numbers are constructed:

Base-Ten Mastery Checklist:
[ ] I can count forward to 120 starting from any number.
[ ] I can read and write numerals up to 120.
[ ] I understand that the two digits of a 2-digit number represent amounts of tens and ones.
[ ] I can compare two 2-digit numbers using >, =, and < symbols.
[ ] I can mentally find 10 more and 10 less than any 2-digit number.
[ ] I can add a 2-digit number and a 1-digit number, and add multiples of 10.

Self-Check Reflection

Look at 74: What is 10 more? (84). What is 10 less? (64). Which number is bigger: 74 or 47? (74, because 7 tens beats 4 tens!).

Domain 3: Measurement, Time, and Money

These skills connect numbers to the physical universe:

Measurement and Practical Math Checklist:
[ ] I can order three objects by length from shortest to longest.
[ ] I can measure lengths using non-standard units without leaving gaps or overlaps.
[ ] I can tell and write time to the hour and half-hour on analog and digital clocks.
[ ] I know the names and values of pennies (1¢), nickels (5¢), dimes (10¢), and quarters (25¢).
[ ] I can count collections of mixed coins up to 25¢.

Domain 4: Geometry and Fractions

These skills give you spatial reasoning and fraction foundations:

Geometry & Fractions Checklist:
[ ] I can distinguish between defining attributes (sides, vertices) and non-defining attributes (color, size).
[ ] I can identify and compose 2D shapes (circles, triangles, rectangles, squares, trapezoids, hexagons).
[ ] I can identify 3D solids (cubes, spheres, cylinders, cones) and describe their faces and edges.
[ ] I can partition circles and rectangles into two equal shares (halves) and four equal shares (fourths).
[ ] I understand that 2 halves = 1 whole, and 4 fourths = 1 whole.

Practice Exercises

Exercise 1: Choose one skill from each of the four domains above that you feel strongest in, and explain why you enjoy using it.

Exercise 2: Solve this readiness challenge: What number is 10 more than 89? What number is 10 less than 89?

Exercise 3: Solve this readiness challenge: An analog clock shows the hour hand halfway between 1 and 2, and the minute hand pointing to 6. What time is it?

Exercise 4: Solve this readiness challenge: You have 2 dimes and 1 nickel. How much money do you have in cents? Can you buy a sticker that costs 24¢?

Solutions and Explanations

Solution to Exercise 1: Student reflections will vary; for example, you might choose "making a ten to add" because it lets you add fast in your head, or "partitioning shapes into fourths" because it relates to sharing pizza fairly.

Solution to Exercise 2: 10 more than 89 is 99 (increase the tens digit by 1). 10 less than 89 is 79 (decrease the tens digit by 1).

Solution to Exercise 3: The time is 1:30 (half-past one). The hour hand has passed 1 but not reached 2, and the minute hand on 6 indicates 30 minutes.

Solution to Exercise 4: 2 dimes equal 20¢ (10¢ + 10¢), and 1 nickel equals 5¢, giving a total of 25¢ (20¢ + 5¢ = 25¢). Yes, you can buy the 24¢ sticker because 25¢ is greater than 24¢ (25 > 24), and you will even receive 1¢ in change!
