Adding Multiples of 10’s and 100’s --- Large Flashcards for Larger Numbers. I created these cards to drill my student on adding groups of 10’s and 100’s --- mentally! I set the cards up on an 8 ½ x 11 sheet so that if you just fold it in half down the middle it makes a large flash card --- 8 ½ x 5.5. On one side are the words for the students to figure mentally, the other side shows what the addition problem so the students can check their answers.
The flashcards can be used for whole group practice, small groups or centers, or independent practice. I included a page of suggested uses for each. If you prefer not to make flashcards, the 8 ½ x 11 sheet can be cut in half to create flash cards.
