(3) K-3 Illustrated by Harry Briggs. With its goofy puns, crisp digital artwork, and innovative approach to problem solving, Tang's fourth book of math riddles, geared toward second through fifth graders, is a satisfying addition to the series. Rhyming couplets ask readers to calculate sums of objects (chili peppers, clams, etc.) by using strategies such as searching for patterns or first grouping, then subtracting. Annotated answers for all puzzles are provided at book's end.

(4) K-3 Illustrated by Harry Briggs. Starting with tulips and moving on through seasonal themes such as fireworks, autumn leaves, and snow flakes, these rhyming couplets, though unfortunately rather forced, encourage readers to add objects by grouping them into twos, threes, fives, or tens. Crisp digital art supports the math strategies, and pages in the back give the answers and explain the best groupings.

Pairs of rhyming couplets describe techniques, like doubling and repeated addition, for the factors zero to ten. Sample problems are followed by challenges for the reader.

(3) K-3 Illustrated by Harry Briggs. Clever rhymes ask readers to solve math problems by using counting and addition strategies that include grouping, subtracting, and looking for patterns. Sleek illustrations feature different items (i.e., 50 grapes, 16 fish, or 22 snails), providing the focus for each riddle. The math question in each puzzle is highlighted in a different colored font--a helpful visual aid for young readers. Solutions are included.
