2 4.NF.5 4.NF.6 The student is unable to correctly answer any of the parts. The student answers one part correctly. The student correctly represents the decomposition or correctly writes an equivalent equation in one of the questions. OR The student correctly writes equivalent statements for all parts but incorrectly decomposes in just one part. The student correctly: Decomposes the models into hundredths, shading the correct amount. Expresses the equivalence using fractions and decimals: = and 0.3 = 0.30. = and 1.7 = 1.70. 3 4.NF.6 The student is unable to correctly compose or decompose. The student answers one part correctly. The student decomposes 3.24 into just two bonds (3, 0.24) and answers Part (b) correctly. The student correctly: Decomposes 3.24 into number bonds: 3, 0.2, 0.04. Composes 2.53. 4 4.NF.5 The student shows little understanding of the number disks and equivalence. The student models equivalence but does not use number disks. The student shows some understanding of the number disks and supplements with a written explanation. The student correctly uses number disks to show the equivalence of 20 hundredths and 2 tenths in the place value chart. 5 4.NF.5 4.NF.6 The student correctly answers fewer than 10 of the expressions in the chart. The student correctly answers 10 to 14 of the expressions in the chart. The student correctly answers 15 to 19 of the expressions in the chart. The student correctly answers each expression.
