They need to be able to identify parallel, intersecting, and perpendicular, lines. Also acute, obtuse, and right angles and triangles. What a point, line, line segment, and a ray look like and lines of symmetry.
They should practice their math facts by making flash cards or a list of facts.
As far as science they need to know the phases of the moon, how the moon affects the tides, what causes the seasons, the seasons in order, and what causes the night and day pattern. They can search and watch Youtube videos or use google to find information to study all of this. 
Please check your Remind messages for the stuff I have already sent out to have them study. If you need me to add you to the Remind app email me your name and cell number at [email protected]
