The ornamental design for base ten place value frame, as shown and described.

FIG. 1 is a top perspective view of a design for a base ten place value frame shown in a condition of use with the unclaimed base ten elements illustrated.

FIG. 2 is a top perspective view thereof, with the base ten elements removed.

FIG. 3 is a top view of the design with the unclaimed base ten elements shown separately and removed from the base ten place value frame for clarity of illustration.

FIG. 4 is a bottom view of the design.

FIG. 5 is a right side view of the design.

FIG. 6 is a front view of the design; and,

FIG. 7 is a top, rear perspective view of the design shown in a typical environment.

All portions shown in broken lines are environmental and illustrative only and form no part of the claimed design. The left side view is omitted because it is identical to the right side view shown in FIG. 5. The rear view is omitted because it is identical to the front view shown in FIG. 6.
