    The perfect combination for visual learners, this set offers examples of number bonds and blank ten-frame cards on which to practice. Activity ideas suggest using them as a flash card game by showing a ten-frame card and naming the number represented. Use the blank ten-frame cards to play math games such as placing counters in the blank frames to represent what they see on the ten-frame card; throw a die and duplicate the number of dots on your blank card, and more. There are 25 blank ten-frame cards, so the set is great for use with a group. There are 22 pictorial ten-frame cards for teaching or directing the children. Each card measures 7 3/4" x 4 ¾ and is made of sturdy, glossy cardstock. ~ Donna

    The philosophy of the Singapore Math Approach eludes many, but this book breaks it down into bite-sized, understandable pieces so that you can teach your child the math basics in a logical conceptual manner.

    This book explains that math should be taught using the C-P-A Approach – concrete, pictorial, and abstract. Concrete employs manipulatives, pictorial uses visuals or drawings, and lastly, abstract uses math symbols. The idea is that a child cannot do math with symbols until they have adequately worked through the concrete and pictorial methods of doing math. For example, a child will work with blocks or cubes to do basic addition, then use pictures on a page or draw pictures to represent the numbers, then they are ready to do addition problems using the + and = symbols.

    This 122-page book is divided into four chapters, after explaining the philosophy behind the approach. Each chapter deals with the four basic functions – addition, subtraction, multiplication, and division. Within each chapter, activities are presented according to the suggested sequence of stages of the Singapore strategy. For example, the stages of addition are number bonds, decomposing numbers, left-to-right addition, place value disks and charts, vertical addition, and traditional addition. By working through stages in the proper sequence, students will have a better understanding of the function and will master it more quickly.

    The author suggests there are a few manipulatives that will be needed for the activities in this book – place value strips, place value discs, place value charts, number bond cards, part-whole cards, decimal tiles, and decimal strips. She explains how they will be used and even offers suggestions for making your own.

    If you are one of those who have been scared off by the Singapore Approach, this book might alleviate some of the fear. Pretty easy to understand and apply and could be used easily with any curriculum as you try to explain mathematical functions to your children. pb. ~ Donna

    These will remind you of large oversized dominoes and the concept is similar but there are differences (cards have a maximum of ten dots, for starters). These cards (4 ¾ x 7 ¾; rounded corners; black on white background) are designed to provide a pictorial approach to "making 10," i.e. number bonds. Designed to help students internalize the value of numbers and the relationships among those numbers, the dots on the cards are visual representations presented four different ways. The first set depicts the cards divided into ten sections (i.e. two columns of five each). Dots are positioned within the "frames" and progress from a card with one dot to a card with ten dots. The second set has the same progression of dots but this time with empty circles for the non-presented dots. The third set shows the same progression but with only dots on the cards. These first three sets show the dots being added from bottom to top on first the left column and then the right column. The last set of cards shows the dots being added vertically from left to right. ~ Janice

    My favorite thing about this math game is that each bumper car holds a fact family, so children are seeing each whole and its parts together and strengthening those number bonds in their mind every time they play the game. The colorful board is set up like a bumper car arena with tires around the outside and the groups of bumper cars spread around the inside. Cars are grouped by the number of the sum/minuend (whole), and each group shares a common color. The whole appears at the top of the bumper car, with the addends/subtrahends (parts) on the wheels. Some groups may only have one car, such as the "2" group with only a car for 1 and 1, while other groups have up to five: the "10" group has cars for 4 and 6, 3 and 7, 2 and 8, 5 and 5, and 1 and 9. Fact families up to 18 are included. This game can be used to strengthen either addition or subtraction skills.

    To practice addition facts, players spin the spinner twice, reading the addends from the inner section, and then place a token of their color on the bumper car featuring those two parts and their sum in the center. If the car already has another player's token on it, they bump it off and place it in that player's repair shop. If you manage to place tokens on all the bumper cars in a group, you replace your tokens with a school bus and control the group for the rest of the game. A "No brakes!" space on the spinner means you can put your token on the car of your choice that contains the other addend spun. The subtraction game follows the same rules except for you only spin the spinner once, this time using the outer two portions. The outmost section gives you the whole, while the middle portion will show you one part. Students have to solve the equation for the other part, and then place their token on the corresponding car. If two rounds go by with no player able to place a token, the game is over and points are awarded based on the number of cars controlled by each player's buses and tokens. – Steph

    This sturdy learning toy reminds me of the bead maze my kids had many years ago. The rainbow-colored plastic beads teach simple addition and subtraction as you slide them up and over a wood barrier. The barrier is made of 2 removable panels: one side shows colored ovals that match the beads, while the other side shows math problems (add/subtract 0-10). You can play with the beads and slide them over the colored metal arches too! They make a fun sound that kids like. Place the barriers back and practice your math! The overall shape is triangular as you start with one problem and one purple bead, then 2 problems and 2 lilac beads, until you have 10 problems and 10 red beads. 12.5” long x3.25” wide x6” high.

    Math facts can be learned in a number of ways, but can be difficult for some youngsters. This set includes number bond cards for addition and subtraction and part-whole cards. The cards measure 5 inches square and are made of sturdy, glossy cardstock. There are a few blank cards in each set for making your own combinations.

    The number bond cards (80 in the set) are more than flash cards; they show the relationship between addition and subtraction facts. The front of each card presents a diagram with 3 boxes: one box is outlined with a dotted line. The dot-outlined box shows the sum of the other two boxes; the dot-outlined box might instead show one of the addends. The digits you see can be used to explain both the functions of addition and subtraction. The reverse side of the number bond cards show the same diagram as the front, but the dot-outlined number is missing; children name the missing number.

    Part-whole cards (80 cards in the set) show the parts of the whole number. The top half of the card shows the larger number and the bottom half of the card shows the numbers used to make the larger number (for example, 4 and 5 at the bottom and 9 at the top); the cards represent combinations up to 10. The back of each card shows the same number combinations, but one number is missing: children determine the missing number.

    Help your children learn their math facts but also understand the relationship between functions with these helpful card sets. ~ Donna

    Here's a set of Cuisenaire rods for the younger set. These are pretty cute, too! Bigger than regular rods (each ant has a 1" space, so 10 logs are 10" long) – and made of a soft, pliable (and quiet) vinyl material, there are 20 double-sided logs (2 sets of 1-10). Each log has ants on one side and numbers on the other side. Preschool math possibilities abound – matching, sorting, sequencing, counting, "10" number bonds (number family), addition, and subtraction. The logs are 7/8" wide (tall) and about ½" thick. A molded plastic storage tray fits inside the box; a small eight-page activity booklet is included. ~ Janice

    These are very similar in concept to the Number Bond cards – same size (5" squares, rounded corners) but with black ink on white background and covering all combinations from 2 to 10, 80 cards total. One side of the card shows three numbers – with one missing – which are related to the others. The other side has the missing number supplied (and designated by an underline). The cards are designed to show the proportional relationship of the numbers; divided horizontally across the middle of the card; then the lower part divided proportionally. For instance, the 5-5-10 card shows the two fives in equal boxes on the bottom of the card. The 2-5-7 card shows the "2" in a disproportionately smaller section of the bottom than the "5" part. The largest number is always in the upper half of the card. Ideas for using the cards are provided. ~ Janice
