1 · Understandwhat's really being asked

A table and a matching pictograph show the same data for Red, Blue, Green, Gold. The table gives Red = 240, Gold = 310 and total 920, with two cells blank. The pictograph's only filled row, Blue, shows 18 large pictures (10 each) and 0 small pictures (1 each). Completing the table means finding Blue and Green.

Givens

Table: Red = 240, Gold = 310, Total = 920.
Pictograph legend: 1 large picture = 10, 1 small picture = 1.
Blue row (from figure): 18 large pictures and 0 small pictures.
The table and pictograph show the same data.

Unknowns

Blue's amount and Green's amount (to complete the table).

Constraints

The four amounts must add to 920.
Pictograph amounts come from the large/small picture values.

#15 Organize Information in More Ways 3.MD.B.3

Blue shows 18 large pictures and 0 small pictures. Each large is 10 and each small is 1: 18 x 10 = 180 and 0 x 1 = 0, so Blue = 180 + 0 = 180.

18 \times 10 + 0 \times 1 = 180 + 0 = 180

Turning scaled picture symbols into a count is exactly what a scaled pictograph teaches in Grade 3.

2Find Green using the total

#7 Identify Subproblems 3.NBT.A.2

The four amounts add to 920. Subtract the three known amounts: 920 - 240 - 310 - 180 = 190, so Green = 190.

920 - 240 - 310 - 180 = 190

Subtracting the known parts from a known total is Grade 3 place-value work.

3Complete the pictograph rows

#15 Organize Information in More Ways 3.MD.B.3

Convert each amount back into pictures: Red 240 = 24 large + 0 small; Blue 180 = 18 large + 0 small; Green 190 = 19 large + 0 small; Gold 310 = 31 large + 0 small.

10\ \text{per large},\ 1\ \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: Blue = 180, Green = 190

4 · Reviewdoes it hold up?

Add all four: 240 + 180 + 190 + 310 = 920, which matches the given total exactly, so the table is consistent.

Another way: Subproblem order can vary: add the three other amounts first, then subtract from 920 to get Green - same result.

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.

#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.

3 · Execute3 carry out the plan

1Read Dalkom from the pictograph

#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 \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.

2Find Manna using the total

#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.

3000 - 780 - 800 - 690 = 730

Subtracting the known parts from a known total is Grade 3 place-value work.

3Complete the pictograph rows

#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\ \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

4 · Reviewdoes it hold up?

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

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

3.MD.B.3 Draw and interpret scaled picture graphs and bar graphs — Reading the filled row from the scaled symbols and converting amounts back into symbols.
3.NBT.A.2 Fluently add and subtract within 1000 — Subtracting the known amounts from 3000 to find Manna.

💡Takeaway. Each big picture is 100 and each little picture is 10 - count them up, then the total fills in the rest!
