None- TEKS Gaps
Notes from Council
TEKS Gap Alert- This unit is required to fill any GAPS from the
movement to the new TEKS.
**Some listed resources also include multiplying a fraction by a
fraction. The new TEK requires multiplying a whole number by a
fraction, therefore the resources that include multiplying a
fraction by a fraction can be used as an extension.
Process Skills must be incorporated into instruction
as appropriate throughout the school year
