Your next great Lessn starts here.

Welcome to Place Values! – Greetings First Graders! – Learning Place Values up to 100 – We’ll explore numbers 0-100 and their positions – Numbers work together in places – Like a team, each number has a role based on its place – Each place has a value – Ones, Tens, and Hundreds places | This slide introduces first graders to the concept of place values, which is fundamental in understanding the base-ten number system. Start by greeting the students warmly to create an engaging learning environment. Explain that just like how people have different jobs, numbers have different ‘jobs’ or values depending on where they are in a number. Use simple, relatable examples to show how the position of a number changes its value, such as comparing it to seating positions at a table. Emphasize the ones, tens, and hundreds places using visual aids like blocks or charts. This will set the foundation for more complex math concepts and help students become comfortable with larger numbers.

Understanding Place Value – What is place value? – It’s the value of where a digit is in a number. – Value grows by 10 times – Each step to the left increases value 10x. – Exploring ones and tens places – Ones are single units, tens are groups of 10. – Practice with examples – Let’s try with numbers like 15, 29, and 82. | This slide introduces the concept of place value, which is fundamental to understanding numbers in math. Start by explaining that the position of a digit in a number determines its value. Emphasize that as we move from right to left, each place is 10 times greater than the one before. Use visual aids to show the ones and tens places, and provide simple examples that the students can relate to. For instance, use objects like blocks or beads to represent ones and tens. Encourage the students to practice with numbers up to 100, identifying how many ones and tens are in each number. This hands-on activity will help solidify their understanding of place value.

Understanding the Ones Place – What is the ones place? – It shows the number of single units in a number. – Location of the ones place – It’s the rightmost digit in a two-digit number. – Counting with ones – Use items like blocks or beads to count one by one. – Practice with real objects | This slide introduces the concept of the ones place, which is fundamental to understanding place value. Emphasize that the ones place represents single units and is always the rightmost digit in a two-digit number. Use hands-on activities with tangible objects such as blocks, beads, or coins to help students count and visualize the concept of ‘ones.’ Encourage students to group objects in sets of ten to visually differentiate between the ones and tens place. This practical exercise will help solidify their understanding of place value and prepare them for learning about larger numbers.

Understanding the Tens Place – What is the tens place? – It shows groups of ten in a number. – Locating the tens place – It’s the second digit from the right in a two-digit number. – Grouping by tens – Let’s make groups of 10 pencils, 10 blocks, etc. – Practice with objects | This slide introduces the concept of the tens place in a two-digit number, which is crucial for understanding place value. Explain that the tens place indicates how many sets of ten are in a number. Use physical objects like pencils or blocks to visually demonstrate grouping items into sets of ten. This will help students grasp the concept of tens and ones. For example, show 23 as two groups of ten and three individual units. Encourage students to practice with different numbers and objects to solidify their understanding. Prepare to have enough objects for the class activity where students will group items into tens.

Building Numbers with Blocks – Use blocks to build numbers – Each small block equals one unit – Ten small blocks make a big block – Exchange 10 ones for 1 ten-block – Big blocks represent ten units – Understand tens and ones places | This slide introduces the concept of place value using physical blocks, which helps first graders visualize and understand the value of numbers. Each small block represents a single unit, and when students gather ten of these, they can exchange them for a larger block that represents ten units. This exchange illustrates the concept of ‘tens’ and ‘ones’ in a hands-on way. Encourage students to practice building different numbers using the blocks, reinforcing the idea that the position of a number affects its value. For example, the number 23 is composed of 2 big blocks (tens) and 3 small blocks (ones).

Understanding Place Value: Number 45 – Number 45 breakdown – 45 is made of 4 tens and 5 ones – Counting tens and ones – 4 tens = 40 – Groups of ten – 5 ones = 5 – Single units | This slide is aimed at helping first graders understand the concept of place value using the number 45 as an example. Start by explaining that the number 45 is composed of two parts: the tens place and the ones place. There are 4 tens, which is like having 4 bundles of ten sticks, equaling 40. Then there are 5 ones, which are just 5 single sticks. Together, they make up the number 45. Use visuals like blocks or drawings to show 4 groups of ten and 5 single units separately and then combined to form 45. This visual representation will help students grasp the concept of place value more concretely.

Practice Time: Tens and Ones – Now it’s your turn to try! – Find the tens and ones in worksheets – Look for groups of ten and single units – Use blocks to visualize numbers – Blocks stacked together show tens, single blocks show ones – Remember: Each block represents one | This slide is designed to encourage hands-on practice with understanding place value. Students should refer to their worksheets, which will have various numbers up to 100. They need to identify the tens (groups of ten) and ones (individual units). Using physical blocks or drawings of blocks can help them visualize the concept of tens and ones. For example, 43 would be shown as four stacks of ten blocks and three single blocks. Encourage students to count carefully and check their work with a partner. This activity will solidify their understanding of place value and prepare them for more complex math concepts.

Class Activity: Place Value Hunt – Explore the classroom for objects – Group objects into tens and ones – Like pencils or blocks, make groups of 10 – Count how many tens and ones – Use drawings or physical groups to count – Share your findings with the class | This activity is designed to help students understand place value in a tangible and interactive way. Have the students walk around the classroom and collect small objects, such as erasers, pencils, or blocks. They should then group these objects into tens and ones. For example, if a student collects 23 objects, they would make two groups of ten and have three remaining ones. After grouping, students will count and record their findings, then present to the class how many tens and ones they have. This will reinforce their understanding of place value by physically grouping items into tens and ones. Possible variations of the activity could include using different classroom items, grouping into different numbers, or even a scavenger hunt for items with numbers on them to group.

Place Value Mastery Up to 100 – Congratulations on learning place values! – Grasping tens and ones is crucial – Knowing this helps with numbers beyond 100 – Practice makes perfect in place values – Keep playing games and solving problems – You’re on your way to becoming pros! | This slide is meant to congratulate the students on their hard work learning about place values up to 100. Emphasize the importance of understanding the concepts of tens and ones as foundational skills for working with larger numbers. Encourage them to continue practicing with various activities such as place value games, puzzles, and worksheets to reinforce their learning. Acknowledge their progress and assure them that with continued practice, they will become proficient in place values, setting a strong foundation for future math skills.
