I have found the following books to be quite useful to supplement classroom lessons on

**whole number Operations (addition).**

**Books**

Domino Addition. Auth. by Lynette Long. 32 pages. Charlesbridge Publishing Inc. 1997. (978-0881063523). Gr. K-2

Each opening is the same: "Add the number of spots on the top half of each domino to the number of spots on the bottom half of each domino." This pattern follows from 0 through 12, with the appropriate numbers on the featured pieces. Although there's not much in the way of narrative explanation, the concept is presented clearly.

Hershey's Kisses Addition Book. Auth. by Jerry Pallotta. Illust. by Rob Bolster. 32 pages. Scholastic. 2007. (978-0439241731). GR. PK - 3.

Hershey's kisses and miniature clowns introduce simple addition concepts in The Hershey's Kisses Addition Book by Jerry Pallotta, illus. by Rob Bolster. For example, a clown starts out on a skateboard juggling three kisses while his friend, holding one kiss, whizzes past, and all four kisses, plus the knocked-down clowns wind up together in a heap.

M&M's Brand Addition Book. Auth. by Barbara Barbieri McGrath. 32 pages, Charlesbridge Publishing. 2004. (978-0881063486). Gr. K-3.

Mission--Addition. Auth. and illust. by Loreen Leedy. 32 pages. Holiday House. 1999. (978-0823414123). Gr. 1-3.

Miss Prime and her class of animal students learn to add by playing detective and counting clues, taking a class survey, inventing word problems, and figuring out a lunch bill; two other situations focus on adding the profits of a yard sale and keeping score in a game. Although the breaks between the different scenes are not very well delineated, Leedy's explanations are clear and concise, and her colorful pictures feature a bevy of amusing animals.

1+1= 5 : and Other Unlikely Additions. Auth. by David LaRochelle. Illust. by Brenda Sexton. 32 pages. Sterling. 2010. (978-1402759956). Gr. K-2.

This clever concept book asks children to take a fresh look at simple addition. Are there times when one plus one can equal three and not two? Yes–if you add one unicorn and one goat, you get three horns. Can one plus one ever equal five? Yes, because when you add one set of triplets and one set of twins, you get five babies. After sharing the numerous examples provided, children can be asked to stretch their imaginations and come up with their own quirky equations. Sexton's brightly colored digitally rendered cartoon-like illustrations are not only cheerful and attractive, but they also provide subtle clues.

*Websites**I think that the students will enjoy the last 4 links because of the graphics and pace. Prove me wrong!*

Addition Dragons

Shoot down the dragons to keep the castle safe. Wrong answers bring the dragons closer and closer to the castle.

Addition Sharks

Students can choose to play the game by adding two digit numbers, 2 and 1 digit numbers, or practice 1-5 =, or 6-10 facts. The first player with 20 correct answers wins!

Addition Washington Monument Game

To guide your hot air balloon over the 555 foot Washington Monument, the student must correctly answer addition problems to elevate the balloon. Don't make too many miscalculations, peril is eminent.

**Central Park Fun**

Students are given an addition question and the answer is flying somewhere over the park on a blimp. Click the correct blimp to score points and hone in your skills.

Math Marbles

This is a fun counting game where the students are asked an addition problem with 3 answer options. They can drag a marble and put it in the box to represent the numeric answer.

*Background Information*· Building an understanding of the algorithm by first using concrete materials and then a do-and-write approach connects it to the written form of the algorithm.

· The traditional algorithm for two-digit numbers is contrary to the natural inclination to begin with the left-hand number.

· Regrouping is used in addition when a sum in a particular place value is 10 or greater.

*For the Teacher***2.6 The student, given two whole numbers whose sum is 99 or less, will**

a) estimate the sum; and

b) find the sum, using various methods of calculation.
