Compare Two-Digit Numbers

In this topic, students will:

• find numbers that are more or less than a given number

• use a hundred chart to find 1 more, 1 less, 10 more, or 10 less 

• use place-value blocks to compare 2 two-digit numbers

• compare two numbers using a greater than, less than, or an equal sign

• compare and write two-digit numbers that are greater than or less than other two-digit numbers

Vocabulary:

Less - the value of the number is smaller

Compare - to determine whether a number is smaller, greater, or equal to another number

Greater than - the number is more than the other number

Less than - the number is smaller than the other number

At-home Practice:

Supplies:

•  deck of cards

Give each player 8 cards. Place the remaining cards in a stack. Player 1 selects two of his/her cards to make a two-digit number and places them on the playing surface. (ex. He chooses a 4 and a 7 to make the number 47.) Player 2 then looks for 2 cards in his/her hand to make into a two-digit number that is greater than Player 1’s number. If successful, Player 2 wins all four cards. If not, Player 1 wins the cards. Draw new cards from the pile to keep 8 cards in each player’s hand. Player 2 begins the next round. The player with the most cards wins.
