My kids aged 5 and 6 really enjoyed the book. Especially since i doubled up the reading with a simultaneous activity with 12 dolls/toy figures put together in a line. As we read, the kids arranged the 12 dolls in the same manner that the teacher in the book wants from her students. My younger child who is not very comfortable with numbers, got to play around with 12 pieces understanding that they can be arranged any which way to add up to 12 all the time. She also taught herself to learn to make x number of rows with equal number of kids. My older daughter immediately got the concept that 4 rows of 3 kids means the number 3 kept in a row 4 times, which i told her means 3 multiplied by 4. Another thing that happened was that the kids learnt the meaning of 'a dozen' and 'pairs' and 'rows'. English is not our mother tongue and though the kids speak english most of the time, specialised words such as these dont get to be spoken.
The book has repeat value as now it has become a 'family game' and they want me to read the book again and again so they can arrange their dolls again and again.
Great book and lots of fun to read aloud. This book could be read as a math book-(division, sets), or, find all the children who are not following the rules, different ways to line up and more. I read it on the first day of school and again when we start division-for first grade. I leave it out for a independent reader's choice book. The kids always like this book both read to them and as a reader. Because of the vocabulary, it is not an easy reader-upper first?. The short length helps lower the reading grade level.
