James Shuler and his minor son Claude appeal from the district court’s 1 dismissal in part, and adverse grant of summary judgment in part, of this civil action under the Individuals with Disabilities Education Act, Section 504 of the Rehabilitation Act, the Americans with Disabilities Act, and other federal and state law. After careful de novo review, we conclude that the district court properly granted the motions to dismiss and for summary judgment, because appellants’ federal claims are either *359 untimely filed or administratively unex-hausted. Further, the district court did not abuse its discretion in declining to exercise supplemental jurisdiction over the remaining state-law claim. As to appellants’ complaint that summary judgment was premature, they did not seek a continuance below under Federal Rule of Civil Procedure 56(f).

Accordingly, we affirm the judgment of the district court, see 8th Cir. R. 47B; and we deny appellee’s request for sanctions under Federal Rule of Appellate Procedure 38.
