10. 1.NBT.B.2
10.2 Counting the value of a digit up to 99
Counting the Value of a Digit up to 99
Discover how the same digit can stand for a different amount depending on whether it sits in the tens place or the ones place.
What You'll Learn
Identify whether a digit sits in the tens place or the ones place before finding its value
Apply the rule that a tens digit's value equals the digit times 10, written \( d \times 10 \)
Recognize that a ones digit's value is simply the digit itself
Calculate a two digit number's total by adding the tens value and ones value, \( 10t + o \)
Compare how the same digit changes value depending on its position, such as the 3 in 35 versus 53
Solve practice problems that ask for the value of one specific digit rather than the whole number
What You'll Practice
1
Counting groups of dots arranged in tens and ones
2
Finding missing numbers in number grids up to 99
3
Identifying numbers based on their place value positions
Why This Matters
Understanding place value up to 99 builds the foundation for all future math. You'll use this skill to add, subtract, compare numbers, and work with money in everyday life and throughout your education.
