Playgroup Queensland brought out the slime, mud and goop and invited Mount Isa families to enjoy a day of messy play.

Programs manager, Andrew McMahon, said the messy day was to help develop and grow motor skills and early maths concepts.

"It also helps young children connect with others through non-verbal play," Mr McMahon said.

"Because messy and sensory play are all about exploring, there's no right or wrong. That means all children can participate - whatever their ability."

Mr McMahon said about 150 children attended the day.

"We are happy with the turn out, in the first 15 minutes we had 70 percent of people who registered check in, and we had a few people show up on the day also," he said.

"The day provided an opportunity for parents to do things which their children that sometimes you cringe doing at home.

"Allowing kids to explore and try out sensory play tests children's skills and allow them to play with things they may not have touched or felt before."

Mr McMahon said playgroups were one of the most popular and enduring grassroots movements for families with young children and were an important part of the early childhood experience.

"The role of Playgroup Queensland is to give families the resources that inspire them to play with their child. Children are active learners and learn through play and when you combine their natural curiosity with a parent or carer's support you are giving a child valuable learning tools for the future," he said.
