Amount by Item (table) Item Maple Oak Pine Birch Total Amount 830 720 2900 Amount by Item (pictograph) Item Amount Maple Oak Pine Birch = 100 = 10
Show solution

Understand

A table and a matching pictograph show the same data for Maple, Oak, Pine, Birch. The table gives Maple = 830, Birch = 720 and total 2900, with two cells blank. The pictograph's only filled row, Oak, shows 6 large pictures (100 each) and 5 small pictures (10 each). Completing the table means finding Oak and Pine.

Givens
  • Table: Maple = 830, Birch = 720, Total = 2900.
  • Pictograph legend: 1 large picture = 100, 1 small picture = 10.
  • Oak row (from figure): 6 large pictures and 5 small pictures.
  • The table and pictograph show the same data.
Unknowns
  • Oak's amount and Pine's amount (to complete the table).
Constraints
  • The four amounts must add to 2900.
  • Pictograph amounts come from the large/small picture values.

Oak shows 6 large pictures and 5 small pictures. Each large is 100 and each small is 10: 6 x 100 = 600 and 5 x 10 = 50, so Oak = 600 + 50 = 650.
6×100+5×10=600+50=6506 \times 100 + 5 \times 10 = 600 + 50 = 650
Turning scaled picture symbols into a count is exactly what a scaled pictograph teaches in Grade 3.
#7 Identify Subproblems 3.NBT.A.2
The four amounts add to 2900. Subtract the three known amounts: 2900 - 830 - 720 - 650 = 700, so Pine = 700.

Convert each amount back into pictures: Maple 830 = 8 large + 3 small; Oak 650 = 6 large + 5 small; Pine 700 = 7 large + 0 small; Birch 720 = 7 large + 2 small.

Answer: Oak = 650, Pine = 700

Review

Add all four: 830 + 650 + 700 + 720 = 2900, which matches the given total exactly, so the table is consistent.

Subproblem order can vary: add the three other amounts first, then subtract from 2900 to get Pine - same result.

Variant 8 answer: Dalkom = 690, Manna = 730

The amounts for each item were surveyed and shown in a table and a pictograph. Complete the table and the pictograph.

Show solution

Understand

A table and a matching pictograph show the same data for Singsing, Manna, Dalkom, Haengbok. The table gives Singsing = 780, Haengbok = 800 and total 3000, with two cells blank. The pictograph's only filled row, Dalkom, shows 6 large pictures (100 each) and 9 small pictures (10 each). Completing the table means finding Dalkom and Manna.

Givens
  • Table: Singsing = 780, Haengbok = 800, Total = 3000.
  • Pictograph legend: 1 large picture = 100, 1 small picture = 10.
  • Dalkom row (from figure): 6 large pictures and 9 small pictures.
  • The table and pictograph show the same data.
Unknowns
  • Dalkom's amount and Manna's amount (to complete the table).
Constraints
  • The four amounts must add to 3000.
  • Pictograph amounts come from the large/small picture values.

Plan

#15 Organize Information in More Ways · also uses: #7 Identify Subproblems

Translate the pictograph picture into a number (Dalkom), then treat 'find Manna' as the remaining subproblem using the total. This is moving between two representations of the same data.

#15 Organize Information in More Ways 3.MD.B.3
Dalkom shows 6 large pictures and 9 small pictures. Each large is 100 and each small is 10: 6 x 100 = 600 and 9 x 10 = 90, so Dalkom = 600 + 90 = 690.
6×100+9×10=600+90=6906 \times 100 + 9 \times 10 = 600 + 90 = 690
Turning scaled picture symbols into a count is exactly what a scaled pictograph teaches in Grade 3.
#7 Identify Subproblems 3.NBT.A.2
The four amounts add to 3000. Subtract the three known amounts: 3000 - 780 - 800 - 690 = 730, so Manna = 730.
3000780800690=7303000 - 780 - 800 - 690 = 730
Subtracting the known parts from a known total is Grade 3 place-value work.
#15 Organize Information in More Ways 3.MD.B.3
Convert each amount back into pictures: Singsing 780 = 7 large + 8 small; Manna 730 = 7 large + 3 small; Dalkom 690 = 6 large + 9 small; Haengbok 800 = 8 large + 0 small.
100 per large, 10 per small100\ \text{per large},\ 10\ \text{per small}
Going from a number back to the right count of large and small symbols is the reverse of reading a pictograph.
Answer: Dalkom = 690, Manna = 730

Review

Add all four: 780 + 730 + 690 + 800 = 3000, which matches the given total exactly, so the table is consistent.

Subproblem order can vary: add the three other amounts first, then subtract from 3000 to get Manna - same result.
