    Oh, the feel of a nice, thick (1 cm.) wooden pattern block! Don't tell your children that these aren't just toys! The bright, enticing primary colors seem to draw even the smallest of our children into play. Proportioned shapes allow for the construction of infinite designs. Even before they begin to use them for "work" on symmetry, congruence, similarity, measurement, fractional relationships, counting, sorting, and geometry, they are discovering the unique relationships between the blocks and getting plenty of experience in patterning and spatial problem-solving. We've had hours of enjoyment with our set and, with 250 blocks to the bucket, there's enough for several children to construct or work simultaneously.

    Young children will appreciate this hands-on approach to developing analytic thinking skills via an exploration of shapes, colors, and patterns. The activities require three types of manipulatives: attribute blocks, pattern blocks, and interlocking (or multilink) cubes. Like the Building Thinking Skills program, activities cover four key areas: Similarities and Differences, Sequences, Classifications, and Analogies. Simple activity instructions appear at the top of each page as a basic guideline for the teacher. The activity book itself is approximately 250 pages. Manipulatives are not included. Required manipulatives for this program are as follows: A) Pattern Blocks – set of 100 in six colors and shapes (triangle, trapezoid, rhombus (2 types), hexagon, square); B) Interlocking Cubes – set of 100 (plastic cubes that link on all sides, 10 cubes of 10 different colors); C) Attribute Blocks – set of 60 (pieces come in 5 shapes (triangle, square, rectangle, circle, hexagon), 3 colors (red, blue, yellow), 2 sizes (large, small), 2 thicknesses). ~ Anh

    Cute plastic bears in three sizes, three weights, and six colors (red, orange, yellow, green, blue, purple). Baby bear weighs 4 grams, mama weighs 8 grams, and papa weighs 12 grams. Proportional weights allow use on balance for measurement discoveries ("How many babies weigh as much as mama and papa?"). We recommend doing these activities on a pan balance, not a teeter-totter type balance where placement of the bears is crucial (and potentially frustrating for young children). Rainbow set includes 24 papa, 24 mama, and 48 baby bear counters and is packaged in a resealable bag. Note that although the bears are slightly different in appearance (bears are standing and wearing backpacks) to the ones featured on the Three Bear Family Sorting and Pattern cards below, the sizes, colors and weights are identical.

    Rainbow Price: $8.95

    A great complement to the hundred number chart, these quality plastic tiles were one of Mark's favorite math manipulatives when he was learning to count to 100. Sorting them into stacks of 10 helped him understand the concept of place value. Turning random tiles upside down helped him learn "What's between ___ and ___?". Tiles are the right size to fit in the squares on the hundred number chart. "Dad, can we use the tiles today?"

    This 61-pc set allows children to work tactilely with fractions by applying them to circles. Plastic pieces include an avocado green whole, blue halves, green thirds, peach fourths, magenta fifths, orange sixths, pink eighths, highlighter green tenths, and purple twelfths. A transparent cylindrical box with lid holds the whole set. Show equivalents by placing the whole piece in the bottom and see what combinations of other fractions will fill the circle. You could also enhance the pieces by adding magnets to the back. ~ Ruth

      Learning fractions, decimals and percentages and seeing the connections between them can be challenging. They were for me! Manipulatives such as these can be just the aid needed to help students grasp the concepts. This set includes three tile sets: fractions, decimals, and percentages. The tiles correlate in shape and color. So, to build a tile that represents the large “1” blue tile (6” long), your student can use twelve 1/12 pink tiles, six 0.166 orange tiles, or eight 12.5% tiles. You can also show correlation with colors: the yellow tiles are 2.5%, ¼, and 0.25. So helpful to bridge between the three equivalents! I would personally add magnets to the tile backs for further usability. Colors, from largest to smallest, are blue, brown, black, yellow, green, orange, red, purple and pink. Nine different fractions (and their equivalents) included: 1, ½, 1/3, ¼, 1/5, 1/6 1/8, 1/10, and 1/12. Tiles are 1” tall and range from 6” long for the “1” (or whole) tile to 1/2” long for the 1/12 tile. Comes in a transparent, plastic storage case with attached lid (bottom is 6 ¼” x 4 ¼”; top of case is 6 ½ x 4 ½). ~ Ruth

    If you prefer Cuisenaire rods in two-dimensional form, then you've come to the right place. This set contains 64 rods as flat magnets – perfect for presentations on a magnetic board or the fridge. This set includes standard Cuisenaire rod colors and increments, although the measurements have been proportionally enlarged for demonstration purposes. In a standard set of Cuisenaire Rods, the shortest Rod (white), is 1 cm long and the largest (orange) is 10 cm long. In this magnetic set, the white Rod has been enlarged to 2.5 cm x 2.5 cm and the orange Rod has been enlarged to 25 cm x 2.5 cm. ~ Lisa

    Designed to provide reinforcing activities for students learning the basic number bonds, these sets of 80 cards each are 5" squares with rounded corners; colored ink on white background. Each card depicts three numbers (in boxes) with lines showing the bond relationship for instance, 7, 6, and 1. Cards are shown three ways; once with "7" missing; once with "6" missing, and once with "1" missing. The backside of each card supplies the "answer" or missing bond member. All bond combinations from 2 to 10 are depicted. Several blank cards, still showing bond relationships, can be used to make additional cards using dry-erase markers (cards are laminated). Ideas for using the cards are provided. ~ Janice
