Things to Consider Before Buying an Erector Set Toy for Your Kids

Beyond buying your child an erector set, its highly important to make sure that you are getting one that suits your child’s age, abilities and needs. If you get one that is too easy for them, it will be totally unchallenging, unexciting and in the long run boring. If you get one that’s too difficult for your kid to decipher, they will be put off, unhappy and possibly believe they aren’t good enough which might lead to low self-esteem and morale, lack of confidence and a loss of interest in STEM matters.

Tips on How to Choose an Erector Set for your 7 year old

  1. Just as stated above, the complexity level differs from one to another, therefore as a parent, you should find out some information about the difficulty level of the toy.
  2. Choose themes that your kids are familiar with. For example, if your kid loves robots, then a robot erector set will be a perfect gift like the Meccano Erector MeccaSpider Set. If the interest is on trucks and cars, a vehicle theme is a must, such as Meccano Erector 4×4 Truck Model.
  3. You might want to go for well known manufacturers; some of which are Meccano, Erector, K’NEX, Eitech and Engino.
