This activity allows you both to spend time with your child and to make him aware that you can make things instead of buying them. However, make sure your child is not allergic to eggs before starting the activity.
We need :
- well-washed eggshells with soap and water (to prevent salmonellosis);
- a pestle and a mortar to grind the eggshells (you can also crush them with a bowl);
- plaster of Paris or flour;
- of water.
Well-cleaned and dry eggshells can be stored for a long time. Collect them so that you can prepare a large amount of chalk.
How to do?
- Altogether remove the membrane from the eggshells.
- Grind the shells until a fine powder is obtained.
- Mix 2 parts of flour or plaster with one part of eggshell powder.
- Add enough water to form a hard paste.
- Shape the dough into sticks.
- Cover with plastic wrap and allow it to dry.
- To make colored chalks, add powder paint before pouring the water.
To do during the preparation of the chalk:
While you prepare the chalk, discuss with your child the ingredients and their characteristics (texture, odor, etc.). As you add the ingredients, let them know what happens when they are combined.
To do once the chalk is ready:
This chalk is perfectly suited for outdoor use on the sidewalk or the paved surface of the garage access. Use the chalk sticks to make drawings, or to play hopscotch or tic-tac-toe! They also work very well on construction paper.
This activity puts into practice the parenting approach Comfort, play and teaches, and participates in your child’s development in the following way:
By spending time preparing chalk and playing with your child, you make him feel that he is important to you and that you love him.
Have fun preparing chalk with your child, then inventing all kinds of games together. Encourage your child to use his imagination.
Any activity that requires mixing ingredients is useful for teaching. For example, you can introduce the elements and their characteristics to your child, and then let them observe what happens when they are combined. It also shows him that it can be fun to do things with his hands.
