Answer Key — The Cosmic Block Caper
- Clue 1 (Rounding): "THE VILLAIN DOES NOT HAVE OBSIDIAN SHIELD"Round 694 to the nearest hundred = 700 (T) · Round 1,685 to the nearest hundred = 1700 (S) · Round 166 to the nearest ten = 170 (E) · Round 2,093 to the nearest thousand = 2000 (H) · Round 47 to the nearest ten = 50 (V) · Round 1,144 to the nearest hundred = 1100 (N) · Round 111 to the nearest ten = 110 (L) · Round 23 to the nearest ten = 20 (A) · Round 67 to the nearest ten = 70 (B) · Round 88 to the nearest ten = 90 (I) · Round 127 to the nearest ten = 130 (D) · Round 280 to the nearest hundred = 300 (O)
- Clue 2 (Multi-step word problems): "RIGHT HANDED"There were 100 space crystals in all. 2 Moon Miners used 15 space crystals each. The other 2 Moon Miners shared the rest equally. How many space crystals did each of the other Moon Miners get? = 35 (R) · Astronaut earned 2 redstone dust in each of 2 rounds, plus 24 bonus redstone dust. Then 13 redstone dust were lost. How many redstone dust are left? = 15 (N) · Astronaut collected 26 redstone dust in the morning and 106 redstone dust in the afternoon, then split them equally among 2 Moon Miners. How many redstone dust did each get? = 66 (A) · There were 101 iron ingots in all. 3 Moon Miners used 9 iron ingots each. The other 2 Moon Miners shared the rest equally. How many iron ingots did each of the other Moon Miners get? = 37 (T) · Astronaut earned 7 iron ingots in each of 3 rounds, plus 12 bonus iron ingots. Then 6 iron ingots were lost. How many iron ingots are left? = 27 (I) · Astronaut filled 7 boxes with 6 energy cells each, then found 36 more energy cells. How many energy cells are there in all? = 78 (H) · There were 311 moon rocks in all. 17 moon rocks were set aside. The rest were shared equally among 6 Moon Miners. How many moon rocks did each get? = 49 (G)
- Clue 3 (Addition): "A LIGHTED REDSTONE TORCH SCARED THEM OFF"3532 + 2345 = 5877 (A) · 1430 + 3250 = 4680 (R) · 2021 + 984 = 3005 (N) · 1945 + 3028 = 4973 (G) · 2083 + 3316 = 5399 (C) · 2047 + 4372 = 6419 (S) · 4986 + 2563 = 7549 (I) · 3447 + 3878 = 7325 (H) · 5377 + 4520 = 9897 (M) · 2267 + 1720 = 3987 (E) · 3615 + 2564 = 6179 (T) · 6318 + 3241 = 9559 (O) · 4017 + 4827 = 8844 (L) · 4004 + 2704 = 6708 (F) · 4664 + 2377 = 7041 (D)
- Clue 4 (Subtraction): "SILVER SPACESUIT THREADS WERE ON THE LATCH"9761 - 3118 = 6643 (S) · 5523 - 1367 = 4156 (C) · 4507 - 679 = 3828 (L) · 8648 - 3858 = 4790 (U) · 5868 - 4038 = 1830 (T) · 3789 - 1505 = 2284 (P) · 7213 - 1550 = 5663 (V) · 8820 - 1402 = 7418 (D) · 8054 - 2386 = 5668 (I) · 4806 - 1070 = 3736 (N) · 7143 - 2752 = 4391 (R) · 3281 - 1295 = 1986 (A) · 8357 - 2650 = 5707 (W) · 12983 - 4164 = 8819 (E) · 5192 - 3034 = 2158 (O) · 6569 - 1259 = 5310 (H)
- Clue 5 (Division facts (1-12)): surviving statement (box 5) → Kalpana Chawla10 ÷ 5 = 2 · 12 ÷ 3 = 4 · 108 ÷ 12 = 9 · 5 ÷ 5 = 1 · 15 ÷ 5 = 3 · 50 ÷ 5 = 10 · 40 ÷ 5 = 8 · 6 ÷ 1 = 6 · 60 ÷ 5 = 12 · 77 ÷ 7 = 11 · 21 ÷ 3 = 7
