Place Value: I'm Thinking of a Number - Set 2 This is the second of six different sets of "I'm Thinking of a Number Cards" to use when teaching place value. This set uses 2 digit numbers and includes comparing numbers. Clues may have one solution, multiple solutions or no solution. I use the cards in a small group at first and have them build the number on a place value mat with base ten blocks. We discuss how they determined the number from the clues. Students may use a hundreds chart inste

Place Value: I'm Thinking of a Number - Set 1 This is the first of six different sets of "I'm Thinking of a Number Cards" to use when teaching place value. This set uses only 2 digit numbers. I use the cards in a small group at first and have them build the number on a place value mat with base ten blocks. We discuss how they determined the number from the clues. When the activity is moved to a center, students shuffle the cards, draw one card, build the number on their place value charts a

Place Value: I'm Thinking of a Number - Set 4 This is the fourth of six different sets of "I'm Thinking of a Number Cards" to use when teaching place value. This set uses 3 digit numbers. These clues have only one solution. I use the cards in a small group at first and have them build the number on a place value mat with base ten blocks. We discuss how they determined the number from the clues. When the activity is moved to a center, students shuffle the cards, draw one card, build the num

Place Value: I'm Thinking of a Number - Set 3 This is the third of six different sets of "I'm Thinking of a Number Cards" to use when teaching place value. This set uses 2 digit numbers and includes comparing numbers, odd and even numbers and differences. Clues may have one solution, multiple solutions or no solution. I use the cards in a small group at first and have them build the number on a place value mat with base ten blocks. We discuss how they determined the number from the clues. St

I Have Who Has cards are a great way to practice content skills, mental math and listening skills. It is one of the few whole group activities where it is mandatory that you participate all the time or it won't work. In the beginning, give students time to build their number on their place value mat. When someone calls out their base ten block pieces, they'll be ready. When they become more proficient with place value, most of them won't need the blocks. I use a stopwatch and time how long

Place Value: I'm Thinking of a Number - Set 6 This is the sixth of six different sets of "I'm Thinking of a Number Cards" to use when teaching place value. This set uses 3 digit numbers, odd and even numbers and the sum of digits in the clues. These clues may have more than one solution. I use the cards in a small group at first and have them build the number on a place value mat with base ten blocks. We discuss how they determined the number from the clues. When the activity is moved to

This is a set of Hundreds Charts with the numbers from 1-1000 to be used with my "I'm Thinking of a Number" sets four through six. The three digit-numbers in these sets are large enough to make using base ten blocks cumbersome.

These cards can be used to play five different place value activities: • Rummy • Memory or Concentration Game • Go Fish • Mingle • Matching Students match numerals, base ten block representations and words for the numbers from 11 to 100. The set contains number, picture and word cards for 11-100, directions for the activities and a student response sheet.

This lesson uses the children's literature book One Watermelon Seed in a hands-on activity reinforcing counting, patterns, skip counting and problem solving. It can be used as a whole class activity with students working in pairs to do the counting. After introducing this lesson, any counting book can then be used in a math center or station with extension questions to create a new problem solving activity. Included are the lesson notes, a place value chart and a counting mat that students us
