The Bone Vault is a location and an activity in JumpStart 2nd Grade. It is designed to teach math and spelling skills for second graders.

Characters

Description

The player must solve math and spelling problems to open the locks on the bone vault. First the player must click on the red dial on the rotary combination lock to begin. Then the player must press the dial to stop on the correct number or letter that completes the problem.

In math mode, the player must find the number to solve the equation. In spelling mode, the player must find the vowel that correctly fills the blank in a word.

When the vault has been opened, a ton of bones spill out, revealing the Measuring and Weighing Room. In this room, the player can use a ruler to find the length of objects, and a scale to find the weight of objects. These measurements can used to complete certain pen pal challenges.

There are eight items that can be measured:

  • Soda Can
  • Television
  • Shoe
  • Football
  • Basketball
  • Hammer
  • Pencil
  • Brick

Difficulty level differences

  • Scout - Features single dials only. Players only use addition to solve math problems. For spelling, players complete three-letter words.
  • Explorer - Features single and double dials. Players use addition and subtraction to solve math problems. For spelling, players complete five-letter words.
  • Trailblazer - Features single and double dials. Players use addition, subtraction, and multiplication to solve math problems.

The Measuring and Weighing Room

This exciting room is in the Bone Vault. The scale and ruler are just what you need to help answer Pen Pal challenges.

  • Use the ruler to measure the length, width or height of objects.
  • Click on the ruler once to pick it up, then click again to drop it on an object. If the ruler cannot be dropped on an object, then it cannot be weighed in the Bone Vault.
  • Use the scale to weigh objects.
  • Click on an object and drag it over to the scale.
  • Click again to learn how much it weighs. If an object cannot be picked up, it cannot be weighed.
  • Click once more to return them to their original places.
  • Click the Green Arrow to exit.
