To make chalk using cassava, first, the cassava roots are peeled, washed, and then grated or ground into a pulp. The pulp is then mixed with water and allowed to settle, separating the starch from the fibrous material. The starch is collected, dried, and then processed further, often by mixing it with calcium carbonate or other fillers to achieve the desired chalk consistency. Finally, the mixture is shaped into sticks or powder and allowed to dry completely before use.
