Freckle Adaptive Math practice allows students to practice their math skills across different topics. The best part is - Freckle adapts while they work! All students start with a pre-test in each domain, or group of topics. The pre-test determines their starting level. But, as students work in each domain, Freckle is constantly adjusting to them. Freckle provides students with remediation problems when they are struggling, and pushes them onto more advanced concepts when they are doing well.
