This set includes the following four centers:
Ghostly Addition: Addition facts to make numbers 5-20.
Base 10 Match-up: A matching activity that requires students to match numbers 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 to cards with base ten blocks on them.
Base 10 Match-up 2: This activity includes three sets of cards. One has numbers 10-30, another is a set with base-10 blocks for numbers 10-30, and the last is a set of cards that lists the numbers of tens and ones for numbers 10-30. The set can be used to ask students to match numbers to base ten blocks, numbers to tens and ones, or number of tens and ones to base ten blocks. I have also used combinations of two sets of cards to play memory games with my students.
Monster Money: This activity also includes three sets of cards. One set that has cards with combinations of coins (pennies and dimes) to make amounts of 11¢ to 30¢, another with amounts 11¢ to 30¢ written out, and a third with cards that have pictures of candy with values of 11¢ to 30¢. The cards can be used to ask students to match coin amounts to values or match coin amounts to candy. I have also used either the coin cards and number cards or coin cards and candy cards together to play memory games with my students
