A number talk is a short (10-15 minute), ongoing daily routine that provides students with meaningful practice with computation. Tools should be used during second grade number talks to provide a context for reasoning with numbers. Some examples of tools appropriate for second grade are rekenreks, ten-frames, double ten-frames, open number lines, and hundred charts.
Differences Between Shingles and Hives. Shingles is caused by the varicella zoster virus, same as chicken pox. Hives are a skin reaction to many different things, including pets, soaps, foods, and medications. 2. Hives cause red and itchy welts to form on parts of the skin but do not cause blisters.
Although the earliest appearance of shingles symptoms is sometimes confused with hives (raised areas of itchy skin), bedbug bites, or scabies (skin infection by scabies mite), the classic pain, and blistering in a band on one side of the body may be all that is necessary for a doctor to clinically diagnose herpes zoster infection (shingles).
