Introducing Place value of Thousand
Objective 1: Make them apply the concept of place value by giving them simple word based riddles which will help them realize how numbers grow.
reaffirm the concept of place value with puzzles and make them understand the number value increases with number getting added on the left side.

Step 1: Keep the number cards on your table and ask students to tell you which number will come under the particular place value. You can start this exercise with two digit numbers followed with couple of three digit numbers.Then, have your student tell you what number is in each place and the value of that number

For example: if the number is 75, there is a 7 in the tens place and the value of that number is 7 tens or 70). Keep dictating numbers, but each time increase the number of digits. Start with a two-digit number, increase it to a three-digit number, and so on, until you get to the millions place (as per your class’ requirement). For each round of the game, be sure to ask your child to say the number aloud after she makes it with the number cards. Once she’s gotten a bunch of practice, turn the tables. Have her dictate number to you!
Step 2: Tell your child to make the largest and the smallest two-digit, three-digit, four-digit number she can.
Step 3: Dictate a number. Have your students set up the cards to show that number. Then, tell your child to increase or decrease the number by different values.

For example:If you dictate the number 2,345, ask her to increase the number by 1,000. She should replace the 2 with a 3, making the new number 3,345. Reverse roles with your Students.

Step 4: Come up with a place value riddle for your child to figure out. Give her clues to help her guess the number you have in mind.

For example: “I am a four-digit number. I have a 2 in my hundreds place, no value in my tens place, and an 8 in my ones place. If the sum of my number’s digits is 17, what’s my number? (answer: 7,208) Now, have your child write or dictate her own place value riddle for you to figure out!
