Great Games and Accessories for the PC.Learning Ladder Years 1 and 2 is an extremely good CD-ROM aimed at children aged 5-7. It presents a huge number of activities that would help to support the school curriculum.

Children can navigate their way around the playroom, which will develop their confidence with the mouse. Children will enjoy making things move on the screen. There is also a range of fun activities, such as painting and copying the tune.

The program also helps to consolidate and reinforce what children are learning in literacy, numeracy and science at school. There are games involving identifying sounds, making words, addition, subtraction, multiplication and division and much more. Children are rewarded with stickers as they complete activities correctly, which they will love collecting and putting in their own sticker book. --Amanda York

Zoombinis Maths Journey features uncommonly fun reasoning games that require serious problem solving and maths work. This CD-ROM employs basic fundamentals of mathematical thinking while keeping children thoroughly entertained throughout.

Not too long ago, Zoombinis enjoyed the good life. Though they all looked slightly different--different eyes, noses, hair, feet--such differences meant nothing to the Zoombinis. And so they lived happily on Zoombini Isle, making small, useful products, which were prized the world over.

So begins this unsuspectingly addictive CD-ROM, yet the perils that face this cheerful society are not as fearsome as the amount of time you'll potentially spend on this pursuit. Beware the chubby, chattering Zoombinis if you don't want to get hooked to your computer for at least 90 minutes a session.

Adored by educators and parents alike, Zoombinis Maths Journey challenges children to employ such basic fundamentals of mathematical thinking as organising information, reasoning of evidence, finding and making patterns, and systematic testing of hypotheses. The journey follows four puzzle-filled trails, each exploring related mathematical ideas. The fundamental data and variables for all this work are the variations in the Zoombinis' features. Their "feet", for example, can be shoes, skates, whirligigs, or coiled springs (the sound effects for these items are particularly great), while their "eyes" may be heavily lidded, enhanced by eyeglasses, blocked by dark shades, or limited to just a single eyeball. Sorting and arranging these variables in order to solve puzzles requires concentrated effort from the players and the game rewards them well with inventive scenarios that evolve in fabulously curious ways as skills are gained. This may not sound like much, but when Arno the Pizza-Eating Tree Troll, who has been yammering for the perfectly topped pizza his entire lifetime, suddenly demands a perfectly topped ice cream sundae, too, it is a staggering, giddy surprise.

The product is full of so many little joys, it's hard to demand improvements. Still, it'd be a great thing if version 2 would feature something other than the monotonous, ping-ping-ping soundtrack that's featured here. But that's minor. In the end, the creators' promise that this CD-ROM will "encourage kids to develop a lifetime habit of associating fun with learning" is spot on. (Ages 9 and up) --Jean Lenihan, Amazon.com

Dorling Kindersley has produced yet another outstanding and completely new interactive learning system-- My First CD-ROM: Getting Ready For School--to help children develop key pre-school skills while providing parents with advice and information on child development. It has been written in consultation with Sue Robson, a renowned early years' teacher, educational consultant and author, who is a senior lecturer at the Roehampton Institute.

Meet Zack, a Jack-in-the-box and friendly on-screen guide whose aim is to make learning fun. Hear his clear explanations and animated instructions on how to play the six easy games. Each one can be adapted to suit your child's level of understanding and their fine motor skills. For example, choices can be made between using the mouse or the keyboard, or selecting different speeds or levels of difficulty, choosing between hearing letters as phonetic sounds or as names, and so on. This flexibility enables games to be adapted over and over again as your child's skills develop, so building and developing a child's confidence.

The package is designed for 3-5 year-olds, under parental supervision, or for slightly older children to use on their own. Progress can be monitored and difficulty levels can be adjusted according to age and ability. The games aim to acquaint and help children with the key topics covered in the first year at school, and include number recognition, logic, counting, mathematical language, shapes and sizes, spatial awareness, speaking and listening, letter recognition and letter sounds. Work sheets can be printed out which can extend learning beyond the PC. Buy this package for your youngster, and lay firm foundations with its highly effective approach to parent-assisted learning. --Susan Naylor

Learning Ladder Year 6 is another excellent CD-ROM from Dorling Kindersley. It's aimed at children aged 10-11 and structured so that children listen to a lesson and then carry out exercises that help to consolidate the literacy and numeracy they are learning as part of the school curriculum. This CD-ROM would be invaluable for any child in Year 6 who is preparing for their SATs.

Exercises can be done at five different levels of difficulty, so that children are challenged and continue to make progress. For every 400 points that a child scores, they are rewarded with new pictures to use with the printing machine. As they gather more pictures they can enjoy designing their own cards, invitations and labels, which can be printed out.

Children can also have lots of fun navigating around Science City and learning lots of facts along the way. For example, they can find out about animals, food chains and gravity. The progress tracker clearly shows how each child is getting on with a system of green and red lights. This would quickly show parents where more help is needed. --Amanda York

Join the Zoombinis as they battle to restore the delicate ecosystem on Zoombinis Isle. The Bloats have wreaked havoc, destroying the essential bugs, the "Zerbles", who kept the delicate ecological system intact. Your child must now help restore that balance, by guiding the Zoombinis and their caterpillars through the puzzles and tasks.

The puzzles and tasks take place in the island environment: Zoombinis must decipher hieroglyphs to open gates and guide moths across flower beds, for example, and the activities eventually take them to the Zerble home. At this point, another Zoombini crew begins the journey, following a different path and new activities and tasks. In total, 240 Zoombinis must make the journey to play the grand finale and complete the game. This means children must play at least 20 times (progress can be saved) before reaching this level, and even though this may mean only the most persistent actually finish, there are plenty of learning activities to keep them busy along the way.

Skills covered include decoding, patterns, sequencing, estimating, calculating speed and velocity, using Venn diagrams, organising information, reasoning with evidence, and much more to test and hone mathematical expertise through that most effective method: repetition!

Aimed at children aged 7 years and above, parents may need to help with some of the tasks (and don't worry, a Parent's Guide is included for when you get stuck!). However, with guidance and persistence, even the more difficult activities will prove stimulating and ultimately rewarding. This is a package that really will test children at Maths Key Stage 2 and early Key Stage 3 level, but without the formulaic style of the classroom. --Susan Naylor

Become a Science Explorer is another excellent CD-ROM from Dorling Kindersley aimed at children aged 6-10 years old. Children will love the challenge of going on a mission and trying to become a Science Explorer.

Fizz, the helpful ball of energy, guides children around the different environments where children can carry out activities, answer questions or look at information screens. The graphics are excellent and there is a wealth of scientific information for children to find out in a variety of interesting ways. Children's learning is also cleverly extended when they're given further explanations once they have answered a question.

Children are rewarded with prizes, badges, stickers, rosettes, medals and the ultimate prize of becoming a Science Explorer. They can use their Science Workbook to make scientific observations, answer questions and collect stickers--guaranteed to turn any child into a budding scientist.

There is a range of science experiments that can be printed out and undertaken. These would be ideal for parents to go through with younger children using the comprehensive parents' guide. There are also some very good worksheets, which would help to consolidate children's learning.

Become a Science Explorer is a fantastic CD-ROM that really supports the science curriculum in schools. This would be an excellent buy for parents or teachers of children aged 6-10 years old. --Amanda York
